109-719: Gezira is an island in the Nile , in central Cairo , Egypt . The southern portion of the island contains the Gezira district, and the northern third contains the Zamalek district. Gezira is west of downtown Cairo and Tahrir Square , connected across the Nile by four bridges each on the east and west sides, the Qasr El Nil Bridge , 15 May Bridge, Al-Gala'a Bridge and 6th October Bridge . Under 19th century ruler Khedive Ismail

218-433: A Turkish officer, Selim Bimbashi, were made between 1839 and 1842, and two got to the point about 30 kilometres (20 miles) beyond the present port of Juba , where the country rises and rapids make navigation very difficult. Lake Victoria was first sighted by Europeans in 1858 when British explorer John Hanning Speke reached its southern shore while traveling with Richard Francis Burton to explore central Africa and locate

327-716: A distance of 20 days' journey till it reaches the nearest Ethiopians." Modern exploration of the Nile basin began with the conquest of the northern and central Sudan by the Ottoman viceroy of Egypt, Muhammad Ali , and his sons from 1821 onward. As a result of this, the Blue Nile was known as far as its exit from the Ethiopian foothills and the White Nile as far as the mouth of the Sobat River. Three expeditions under

436-468: A factor of 15 at Aswan. Peak flows of over 8,212 m /s (290,000 cu ft/s) occurred during late August and early September, and minimum flows of about 552 m /s (19,500 cu ft/s) occurred during late April and early May. The Bahr al Ghazal and the Sobat River are the two most important tributaries of the White Nile in terms of discharge. The Bahr al Ghazal's drainage basin

545-402: A sentence, as the object of a verb, or with a preposition. Dependent pronouns are a series of prefixes and suffixes that can attach to verbs and other nouns. Coptic verbs can therefore be said to inflect for the person, number and gender of the subject and the object: a pronominal prefix marks the subject, and a pronominal suffix marks the object, e.g. "I I'have'it the ball." When (as in this case)

654-408: A supralinear stroke ⟨◌̄⟩, or the stroke may have tied letters together in one word, since Coptic texts did not otherwise indicate word divisions. Some scribal traditions use a diaeresis over the letters ⲓ and ⲩ at the beginning of a word or to mark a diphthong. Bohairic uses a superposed point or small stroke known as ϫⲓⲛⲕⲓⲙ ( jinkim , "movement"). When jinkim is placed over a vowel it

763-593: A tenuis-aspirate distinction to voiced-tenuis is only attested from the alveolars, the only place that Arabic has such a contrast. Earlier phases of Egyptian may have contrasted voiceless and voiced bilabial plosives, but the distinction seems to have been lost. Late Egyptian, Demotic and Coptic all interchangeably use their respective graphemes to indicate either sound; for example, Coptic for 'iron' appears alternately as ⲡⲉⲛⲓⲡⲉ , ⲃⲉⲛⲓⲡⲉ and ⲃⲓⲛⲓⲃⲉ . That probably reflects dialect variation. Both letters were interchanged with ⲫ and ϥ to indicate / f / , and ⲃ

872-505: A testament to the increasing cultural contact between Egyptians and Greeks even before Alexander the Great 's conquest of Egypt. Coptic itself, or Old Coptic , takes root in the first century. The transition from the older Egyptian scripts to the newly adapted Coptic alphabet was in part due to the decline of the traditional role played by the priestly class of ancient Egyptian religion , who, unlike most ordinary Egyptians, were literate in

981-534: A vowel's grapheme but mostly unwritten. A few early manuscripts have a letter ⳋ or ⳃ ç where Sahidic and Bohairic have ϣ š . and Akhmimic has ⳉ x . This sound seems to have been lost early on. Coptic is agglutinative with subject–verb–object word order but can be verb–subject–object with the correct preposition in front of the subject. Number, gender, tense, and mood are indicated by prefixes that come from Late Egyptian. The earlier phases of Egyptian did this through suffixation. Some vestiges of

1090-495: Is also better known than that of the Classical phase of the language because of a greater number of sources indicating Egyptian sounds, including cuneiform letters containing transcriptions of Egyptian words and phrases, and Egyptian renderings of Northwest Semitic names. Coptic sounds, in addition, are known from a variety of Coptic-Arabic papyri in which Arabic letters were used to transcribe Coptic and vice versa. They date to

1199-465: Is an archaeological site located in alluvial deposits formed by an ancient channel of the Nile in the Affad region of southern Dongola Reach , Sudan. There are two theories about the age of the integrated Nile. One is that the integrated drainage of the Nile is of young age and that the Nile basin was formerly broken into series of separate basins, only the most northerly of which fed a river following

This fluctuation is caused by the substantial variation in the flow of the Sobat, which has a minimum flow of about 99 m /s (3,500 cu ft/s) in March and a peak flow of over 680 m /s (24,000 cu ft/s) in October. During the dry season (January to June)

1417-516: Is difficult to explain ⟨ ⲏ ⟩ . However, it generally became / æ / in stressed monosyllables, / ɪ / in unstressed monosyllables, and in polysyllables, / æ / when followed by / i / , and / ɪ / when not. There were no doubled orthographic vowels in Mesokemic. Some representative correspondences with Sahidic are: It is not clear if these correspondences reflect distinct pronunciations in Mesokemic, or if they are an imitation of

1526-413: Is expressed with a series of possessive articles which are prefixed to the noun. These articles agree with the person , number , and gender of the possessor and the number and gender of the possessed noun. The forms of the possessive article vary according to dialect. Coptic pronouns are of two kinds, dependent and independent. Independent pronouns are used when the pronoun is acting as the subject of

North of Cairo , the Nile splits into two branches (or distributaries) that feed the Mediterranean: the Rosetta Branch to the west and the Damietta to the east, forming the Nile Delta . The annual sediment transport by the Nile in Egypt has been quantified. Below the confluence with

1744-722: Is likely because the majority of Coptic religious texts are direct translations of Greek works. What invariably attracts the attention of the reader of a Coptic text, especially if it is written in the Sa'idic dialect, is the very liberal use which is made of Greek loan words, of which so few, indeed, are to be found in the Ancient Egyptian language. There Greek loan words occur everywhere in Coptic literature, be it Biblical, liturgical, theological, or non-literary, i.e. legal documents and personal letters. Though nouns and verbs predominate,

1853-425: Is not sufficient to demonstrate that these are distinct vowels, and if they are, the difference has a very low functional load . For dialects that use orthographic ⟨ ⲉⲓ ⟩ for a single vowel, there appears to be no phonetic difference from ⟨ ⲓ ⟩ . Double orthographic vowels are presumed here to be long, as that makes the morphology more straightforward. (Another common interpretation

1962-838: Is possible that in addition there was a glottal stop , ʔ , that was not consistently written. Coptic does not seem to have had a glottal stop at the beginning of orthographically vowel-initial words. It is possible that vowels written double were an attempt to indicate glottal stop, rather than a long vowel, in the middle of a word. However, there is little evidence for this (e.g., Arabic words with short vowels and glottal stop are not written with double vowels in Coptic, and Coptic words with double orthographic vowels are transcribed with long vowels rather than hamza in Arabic.) In Late Coptic (ca. 14th century), Bohairic sounds that did not occur in Egyptian Arabic were lost. A possible shift from

2071-508: Is pronounced independently, and when it is placed over a consonant a short ⲉ precedes it. The oldest Coptic writings date to the pre-Christian era (Old Coptic), though Coptic literature consists mostly of texts written by prominent saints of the Coptic Church such as Anthony the Great, Pachomius the Great and Shenoute. Shenoute helped fully standardise the Coptic language through his many sermons, treatises and homilies, which formed

2180-439: Is safe to assume that the everyday speech of the native population retained, to a greater extent, its indigenous Egyptian character, which is sometimes reflected in Coptic nonecclesiastical documents such as letters and contracts. Coptic provides the clearest indication of Later Egyptian phonology from its writing system, which fully indicates vowel sounds and occasionally stress patterns. The phonological system of Later Egyptian

2289-516: Is that Coptic articles are prefixes. Masculine nouns are marked with the article /pə, peː/ and feminine nouns with the article /tə, teː/ in the Sahidic dialect and /pi, əp/ and /ti, ət/ in the Bohairic dialect. The definite and indefinite articles also indicate number ; however, only definite articles mark gender. Coptic has a number of broken plurals , a vestige of Older Egyptian, but in

2398-405: Is that these represented glottal stop.) There is no length distinction in final stressed position, but only those vowels that occur long appear there: ⟨ (ⲉ)ⲓ, ⲉ, ⲁ, ⲟ~ⲱ, ⲟⲩ ⟩ . In Sahidic, the letter ⲉ was used for short / e / before back fricatives, and also for unstressed schwa / ə / . It's possible there was also a distinction between short / ɛ / and / a / , but if so

2507-572: Is the largest of any of the Nile's sub-basins, measuring 520,000 square kilometers (200,000 sq mi) in size, but it contributes a relatively small amount of water, about 2 m /s (71 cu ft/s) annually, because tremendous volumes of water are lost in the Sudd wetlands. The Sobat River, which joins the Nile a short distance below Lake No, drains about half as much land, 225,000 km (86,900 sq mi), but contributes 412 cubic meters per second (14,500 cu ft/s) annually to

The White Nile is longer and rises in the Great Lakes region. It begins at Lake Victoria and flows through Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at

2725-467: Is usually the result of consonant voicing in proximity to / n / . Though there is no clear evidence that Coptic had a glottal stop , different orthographic means have been posited for indicating one by those who believe that it did: with ⲁ word-initially, with ⲓ word-finally in monosyllabic words in northern dialects and ⲉ in monosyllabic words in Akhmimic and Assiutic, by reduplication of

However, most words of Egyptian origin that entered into Greek and subsequently into other European languages came directly from Ancient Egyptian, often Demotic . An example is the Greek oasis ( ὄασις ), which comes directly from Egyptian wḥꜣt or Demotic wḥj . However, Coptic reborrowed some words of Ancient Egyptian origin into its lexicon, via Greek. For example, both Sahidic and Bohairic use

It had analytic features like definite and indefinite articles and periphrastic verb conjugation. Coptic, therefore, is a reference to both the most recent stage of Egyptian after Demotic and the new writing system that

It has historically been considered the longest river in the world , though this has been contested by research suggesting that the Amazon River is slightly longer. Of the world's major rivers, the Nile is one of the smallest, as measured by annual flow in cubic metres of water. About 6,650 km (4,130 mi) long, its drainage basin covers eleven countries:

3379-456: The discharge at any given point along the main stem depends on many factors including weather, diversions, evaporation and evapotranspiration , and groundwater flow. Upstream from Khartoum (to the south), the river is known as the White Nile , a term also used in a limited sense to describe the section between Lake No and Khartoum. At Khartoum, the river is joined by the Blue Nile . The White Nile starts in equatorial East Africa, and

The source of the Blue Nile is Lake Tana in the Gish Abay region in the Ethiopian Highlands . The source of the White Nile, even after centuries of exploration, remains in dispute. The most remote source that is indisputably a source for the White Nile is the Kagera River ; however,

Shenouda's native Egyptian tongue and knowledge of Greek and rhetoric gave him the necessary tools to elevate Coptic, in content and style, to a literary height nearly equal to the position of the Egyptian language in ancient Egypt. The Muslim conquest of Egypt by Arabs came with

Sahidic Coptic was spoken between the cities of Asyut and Oxyrhynchus and flourished as a literary language across Egypt in

In harsh and arid seasons and droughts, the Blue Nile dries out completely. The flow of the Blue Nile varies considerably over its yearly cycle and is the main contribution to the large natural variation of the Nile flow. During

A canyon, now filled by surface drift, represents the Eonile that flowed during 23–5.3 million years before present. The Eonile transported clastic sediments to the Mediterranean; several natural gas fields have been discovered within these sediments. During the late- Miocene Messinian salinity crisis , when

When the voiced plosives are realised, it

In addition, other Egyptian words that would have adequately translated the Greek equivalents were not used as they were perceived as having overt pagan associations. Old Coptic texts use many such words, phrases and epithets ; for example,

The Nile has been the lifeline of civilization in Egypt since the Stone Age , with most of the population and all of the cities of Egypt developing along those parts of the Nile valley lying north of Aswan. However, the Nile used to run much more westerly through what is now Wadi Hamim and Wadi al Maqar in Libya and flow into the Gulf of Sidra . As

A tune, Hymn to the Nile , was created and sung by the ancient Egyptian peoples about the flooding of the Nile River and all of the miracles it brought to Ancient Egyptian civilization. Water buffalo were introduced from Asia, and the Assyrians introduced camels in the 7th century BCE. These animals were raised for meat and were domesticated and used for ploughing—or in

The northern section of the river flows north almost entirely through the Nubian Desert to Cairo and its large delta , and the river flows into the Mediterranean Sea at Alexandria . Egyptian civilization and Sudanese kingdoms have depended on the river and its annual flooding since ancient times. Most of the population and cities of Egypt lie along those parts of

In Coptic , the word ⲫⲓⲁⲣⲟ , pronounced piaro ( Sahidic ) or phiaro ( Bohairic ), means "the river" (lit. p(h).iar-o "the.canal-great"), and comes from the same ancient name. In Nobiin , the river is called Áman Dawū , meaning "the great water". In Luganda ,

Vitruvius thought that source of the Nile was in Mauritania, on the "other" (south) side of the Atlas Mountains . Various expeditions failed to determine the river's source. Agatharchides records that in the time of Ptolemy II Philadelphus , a military expedition had penetrated far enough along

On an annual basis, the White Nile upstream of Malakal contributes about 15% of the total outflow of the Nile. The average flow of the White Nile at Lake Kawaki Malakal, just below the Sobat River, is 924 m /s (32,600 cu ft/s); the peak flow

6758-444: The afterlife. The east was thought of as a place of birth and growth, and the west was considered the place of death, as the god Ra , the Sun, underwent birth, death, and resurrection each day as he crossed the sky. Thus, all tombs were west of the Nile, because the Egyptians believed that in order to enter the afterlife, they had to be buried on the side that symbolized death. As the Nile was such an important factor in Egyptian life,

6867-482: The ancient calendar was even based on the three cycles of the Nile. These seasons, each consisting of four months of thirty days each, were called Akhet , Peret , and Shemu . Akhet, which means inundation, was the time of the year when the Nile flooded, leaving several layers of fertile soil behind, aiding in agricultural growth. Peret was the growing season, and Shemu, the last season, was the harvest season when there were no rains. Owing to their failure to penetrate

6976-473: The basis of early Coptic literature. The core lexicon of Coptic is Egyptian , most closely related to the preceding Demotic phase of the language. Up to 40% of the vocabulary of literary Coptic is drawn from Greek , but borrowings are not always fully adapted to the Coptic phonological system and may have semantic differences as well. There are instances of Coptic texts having passages that are almost entirely composed from Greek lexical roots. However, that

The Nile was also an important part of ancient Egyptian spiritual life. Hapi was the god of the annual floods, and both he and the pharaoh were thought to control the flooding. The Nile was considered to be a causeway from life to death and

7194-406: The central part of the basin may still be subsiding. The White Nile Rift system, although shallower than the Bahr el Arab rift , is about 9 kilometers (5.6 mi) deep. Geophysical exploration of the Blue Nile Rift System estimated the depth of the sediments to be 5–9 kilometers (3.1–5.6 mi). These basins were not interconnected until their subsidence ceased, and the rate of sediment deposition

The Tabula Rogeriana depicted the source as three lakes in 1154. Europeans began to learn about the origins of the Nile in the 14th century when the Pope sent monks as emissaries to Mongolia who passed India,

7412-492: The development of Egyptian civilization. Because the river overflowed its banks annually and deposited new layers of silt, the surrounding land was very fertile. The Ancient Egyptians cultivated and traded wheat, flax , papyrus and other crops around the Nile. Wheat was a crucial crop in the famine-plagued Middle East. This trading system secured Egypt's diplomatic relationships with other countries and contributed to economic stability. Far-reaching trade has been carried on along

7521-402: The dry season the natural discharge of the Blue Nile can be as low as 113 m /s (4,000 cu ft/s), although upstream dams regulate the flow of the river. During the wet season, the peak flow of the Blue Nile often exceeds 5,663 m /s (200,000 cu ft/s) in late August (a difference of a factor of 50). Before the placement of dams on the river the yearly discharge varied by

7630-410: The etymology is disputed. Homer called the river Αἴγυπτος , Aiguptos , but in subsequent periods, Greek authors referred to its lower course as Neilos ; this term became generalized for the entire river system. Thus, the name may derive from Ancient Egyptian expression n ꜣ r ꜣ w-ḥ ꜣ w(t) (lit. 'the mouths of the front parts'), which referred specifically to the branches of the Nile transversing

Páez's account of the source of the Nile is a long and vivid account of Ethiopia. It was published in full only in the early 20th century, although it was featured in works of Páez's contemporaries, including Baltazar Téllez, Athanasius Kircher and Johann Michael Vansleb . Europeans had been resident in Ethiopia since

7848-488: The functional load was extremely low. Bohairic did not have long vowels. / i / was only written ⟨ ⲓ ⟩ . As above, it's possible that / u / and / o / were distinct vowels rather than just allophones. In Late Coptic (that is, Late Bohairic), the vowels were reduced to those found in Egyptian Arabic, /a, i, u/ . ⟨ ⲱ, ⲟ ⟩ became / u / , ⟨ ⲉ ⟩ became / æ / , and ⟨ ⲏ ⟩ became either / ɪ / or / æ / . It

7957-459: The great lakes. Believing he had found the source of the Nile on seeing this "vast expanse of open water" for the first time, Speke named the lake after Queen Victoria . Burton, recovering from illness and resting further south on the shores of Lake Tanganyika , was outraged that Speke claimed to have proven his discovery to be the true source of the Nile when Burton regarded this as still unsettled. A quarrel ensued which sparked intense debate within

8066-499: The island was first called "Jardin des Plantes" (French for "Garden of Plants"), because of its great collection of exotic plants shipped from all over the world. Schools on the island include: Gezira Island is home to the basketball club Al Gezira Cairo , 2017 Champion of the Egyptian Basketball Super League . Al Ahly SC is located on Gezira island. Nile The Nile (also known as

8175-586: The lake's northern shore. Coptic language Coptic (Bohairic Coptic: ϯⲙⲉⲧⲣⲉⲙⲛ̀ⲭⲏⲙⲓ , Timetremənkhēmi ) is an Afroasiatic extinct language . It is a group of closely related Egyptian dialects , representing the most recent developments of the Egyptian language , and historically spoken by the Copts , starting from the third century AD in Roman Egypt . Coptic was supplanted by Arabic as

8284-417: The language retained an important position, and many hagiographic texts were also composed during this period. Until the 10th century, Coptic remained the spoken language of the native population outside the capital. The Coptic language massively declined under the hands of Fatimid Caliph Al-Hakim bi-Amr Allah , as part of his campaigns of religious persecution. He issued strict orders completely prohibiting

8393-609: The late 15th century, and one of them may have visited the headwaters even earlier without leaving a written trace. The Portuguese João Bermudes published the first description of the Tis Issat Falls in his 1565 memoirs, compared them to the Nile Falls alluded to in Cicero 's De Republica . Jerónimo Lobo describes the source of the Blue Nile, visiting shortly after Pedro Páez. Telles also uses his account. The White Nile

8502-440: The long Greek vowels ⟨η, ω⟩ . As with the vowels, there are differences of opinion over the correct interpretation of the Coptic consonant letters, particularly with regard to the letters ϫ and ϭ . ϫ is transcribed as ⟨j⟩ in many older Coptic sources and ϭ as ⟨ɡ⟩ or ⟨č⟩ . Lambdin (1983) notes that the current conventional pronunciations are different from

8611-580: The main Nile during the 70,000–80,000 years B.P. wet period. The White Nile system in Bahr El Arab and White Nile Rifts remained a closed lake until the connection of the Victoria Nile to the main system some 12,500 years ago during the African humid period . The Greek historian Herodotus wrote that "Egypt was the gift of the Nile". An unending source of sustenance, it played a crucial role in

8720-422: The majority of cases, the article marks number. Generally, nouns inflected for plurality end in /wə/ , but there are some irregularities. The dual was another feature of earlier Egyptian that survives in Coptic in only few words, such as ⲥⲛⲁⲩ ( snau ) 'two'. Words of Greek origin keep their original grammatical gender, except for neuter nouns, which become masculine in Coptic. Possession of definite nouns

8829-467: The medieval Islamic period, when Coptic was still spoken. There are some differences of opinion among Coptic language scholars on the correct phonetic interpretation of the writing system of Coptic. Differences centre on how to interpret the pairs of letters ⲉ/ⲏ and ⲟ/ⲱ . In the Attic dialect of Ancient Greek in the 5th century BC, the first member of each pair is a short closed vowel /e, o/ , and

8938-513: The original sources of indigo dye . Another may be Nymphaea caerulea , known as "The Sacred Blue Lily of the Nile", which was found scattered over Tutankhamun 's corpse when it was excavated in 1922. Another possible etymology derives from the Semitic term Nahal , meaning "river". Old Libyan has the term lilu , meaning water (in modern Berber ilel ⵉⵍⴻⵍ means sea ). With a total length of about 6,650 km (4,130 mi) between

9047-482: The period c.  325  – c.  800 AD. Bohairic, the language of the Nile Delta , gained prominence in the 9th century and is the dialect used by the Coptic Church. In Coptic the language is called ϯⲙⲉⲧⲣⲉⲙⲛ̀ⲭⲏⲙⲓ ( timetremǹkhēmi ) "Egyptian" or ϯⲁⲥⲡⲓ ⲛ̀ⲣⲉⲙⲛ̀ⲭⲏⲙⲓ ( tiaspi ǹremǹkhēmi ) "the Egyptian language". Coptic also possessed the term ⲅⲩⲡⲧⲓⲟⲥ ( gyptios ) "Egyptian", derived from Greek Αἰγύπτιος ( Aigúptios ). This

9156-575: The present course of the Nile in Egypt and Sudan. Rushdi Said postulates that Egypt supplied most of the waters of the Nile during the early part of its history. The other theory is that the drainage from Ethiopia via rivers equivalent to the Blue Nile, the Atbara and the Takazze flowed to the Mediterranean via the Egyptian Nile since well back into Tertiary times. Salama suggests that during

9265-611: The primary spoken language of Egypt following the Arab conquest of Egypt and was slowly replaced over the centuries. Coptic has no native speakers today, although it remains in daily use as the liturgical language of the Coptic Orthodox Church and of the Coptic Catholic Church . Innovations in grammar and phonology and the influx of Greek loanwords distinguish Coptic from earlier periods of

9374-548: The probable ancient pronunciations: Sahidic ϫ was probably pronounced [ tʲ ] and ϭ was probably pronounced [ kʲ ] . Reintges (2004 , p. 22) suggests that ϫ was pronounced [ tʃ ] . Beside being found in Greek loanwords, the letters ⟨φ, θ, χ⟩ were used in native words for a sequence of /p, t, k/ plus / h / , as in ⲑⲉ = ⲧ-ϩⲉ "the-way" (f.sg.) and ⲫⲟϥ = ⲡ-ϩⲟϥ "the-snake" (m.sg). The letters did not have this use in Bohairic, which used them for single sounds. It

9483-462: The region of Lake Victoria and the Mediterranean Sea , the Nile is among the longest rivers on Earth. The drainage basin of the Nile covers 3,254,555 square kilometers (1,256,591 sq mi), about 10% of the area of Africa. Compared to other major rivers, though, the Nile carries little water (5% of that of the Congo River , for example). The Nile basin is complex, and because of this,

9592-477: The renaissance. Efforts at language revitalisation continue to be undertaken, and have attracted the interest of Copts and linguists in and outside of Egypt. Coptic uses a writing system almost wholly derived from the Greek alphabet , with the addition of a number of letters that have their origins in Demotic Egyptian . This is comparable to the Latin-based Icelandic alphabet , which includes

9701-632: The river is called Kiira or Kiyira . In Runyoro , it is called Kihiira . In Egyptian Arabic , the Nile is called en-Nīl , while in Standard Arabic it is called an-Nīl . In Biblical Hebrew , it is הַיְאוֹר ‎, Ha-Ye'or or הַשִׁיחוֹר ‎, Ha-Shiḥor . The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος . Beyond that, however,

9810-670: The river south-west for over 300 km, following the structure of the Central African Shear Zone embracing the Bayuda Desert . At Al Dabbah it resumes its northward course towards the first cataract at Aswan forming the S-shaped Great Bend of the Nile mentioned by Eratosthenes . In the north of Sudan, the river enters Lake Nasser (known in Sudan as Lake Nubia), the larger part of which

9919-532: The riverbed sufficiently for the river to overflow westward into a depression to create Lake Moeris . Lake Tanganyika drained northwards into the Nile until the Virunga Volcanoes blocked its course in Rwanda. The Nile was much longer at that time, with its furthest headwaters in northern Zambia. The currently existing Nile first flowed during the former parts of the Würm glaciation period. Affad 23

10028-401: The runic letter thorn . There is some variation in the number and forms of these signs depending on the dialect. Some of the letters in the Coptic alphabet that are of Greek origin were normally reserved for Greek words. Old Coptic texts used several graphemes that were not retained in the literary Coptic orthography of later centuries. In Sahidic, syllable boundaries may have been marked by

10137-407: The scientific community and interest by other explorers keen to either confirm or refute Speke's discovery. British explorer and missionary David Livingstone pushed too far west and entered the Congo River system instead. It was ultimately Welsh-American explorer Henry Morton Stanley who confirmed Speke's discovery, circumnavigating Lake Victoria and reporting the great outflow at Ripon Falls on

10246-588: The sea level rose at the end of the most recent ice age , the stream which is now the northern Nile captured the ancestral Nile near Asyut . This change in climate also led to the current extents of the Sahara desert, around 3400 BCE. The Giza pyramid complex originally overlooked a branch of the Nile that no longer exists. This branch was highest during the African Humid Period . The existing Nile has five earlier phases: Flowing north from

10355-516: The second member is a long open vowel /ɛː, ɔː/ . In some interpretations of Coptic phonology, it is assumed that the length difference is primary, with ⲉ/ⲏ /e, eː/ and ⲟ/ⲱ is /o, oː/ . Other scholars argue for a different analysis in which ⲉ/ⲏ and ⲟ/ⲱ are interpreted as /e, ɛ/ and /o, ɔ/ . These two charts show the two theories of Coptic vowel phonology: Dialects vary in their realisation. The difference between [ o ] and [ u ] seems to be allophonic. Evidence

10464-532: The suffix inflection survive in Coptic, mainly to indicate inalienable possession and in some verbs. Compare the Middle Egyptian form *satāpafa 'he chooses' (written stp.f in hieroglyphs) to Coptic (Sahidic) f.sotp ϥⲥⲱⲧⲡ̅ 'he chooses'. All Coptic nouns carry grammatical gender , either masculine or feminine, usually marked through a definite article as in the Romance languages , the difference

10573-429: The temple scriptoria. Old Coptic is represented mostly by non-Christian texts such as Egyptian pagan prayers and magical and astrological papyri. Many of them served as glosses to original hieratic and demotic equivalents. The glosses may have been aimed at non-Egyptian speakers. Under late Roman rule , Diocletian persecuted many Egyptian converts to the new Christian religion , which forced new converts to flee to

10682-530: The territory, except for monasteries located in Nubia . Coptic's most noticeable linguistic influence has been on the various dialects of Egyptian Arabic , which is characterised by a Coptic substratum in lexical , morphological , syntactical , and phonological features. In addition to influencing the grammar, vocabulary and syntax of Egyptian Arabic, Coptic has lent to both Arabic and Modern Hebrew such words as: A few words of Coptic origin are found in

10791-467: The two sounds appear to be in free variation in Coptic, as they were since the Middle Egyptian period. However, they are contrasted only in Greek loans; for example, native Coptic ⲁⲛⲍⲏⲃ ( anzēb ) and ⲁⲛⲥⲏⲃⲉ ( ansēbə ) 'school' are homophonous. Other consonants that sometimes appear to be either in free variation or to have different distributions across dialects are [ t ] and [ d ] , [ ɾ ] and [ l ] (especially in

10900-401: The use of Coptic anywhere, whether in schools, public streets, and even homes, including mothers speaking to their children. Those who did not comply had their tongues cut off. He personally walked the streets of Cairo and eavesdropped on Coptic-speaking homes to find out if any family was speaking Coptic. As a written language, Coptic is thought to have completely given way to Arabic around

11009-560: The western shores of the lake and flows at first to the west until just south of Masindi Port , where the river turns north, then makes a great half circle to the east and north to Karuma Falls . For the remaining part, it flows westerly through the Murchison Falls until it reaches the northern shores of Lake Albert where it forms a significant river delta. Lake Albert is on the border of the Democratic Republic of

11118-441: The word ebenos , which was taken directly from Greek ἔβενος ("ebony"), originally from Egyptian hbnj . Many place names in modern Egypt are Arabic adaptations of their former Coptic names : The Coptic name ⲡⲁⲡⲛⲟⲩⲧⲉ , papnoute (from Egyptian pꜣy-pꜣ-nṯr ), means "belonging to God" or "he of God". It was adapted into Arabic as Babnouda , which remains a common name among Egyptian Copts to this day. It

11227-469: The word ⲧⲃⲁⲓⲧⲱⲩ '(Who is) in (His) Mountain', is an epithet of Anubis . There are also traces of some archaic grammatical features, such as residues of the Demotic relative clause , lack of an indefinite article and possessive use of suffixes. Thus, the transition from the old traditions to the new Christian religion also contributed to the adoption of Greek words into the Coptic religious lexicon. It

11336-526: Was adapted from the Greek alphabet . The earliest attempts to write the Egyptian language using the Greek alphabet are Greek transcriptions of Egyptian proper names, most of which date to the Ptolemaic Kingdom . Scholars frequently refer to this phase as Pre-Coptic. However, it is clear that by the Late Period of ancient Egypt , demotic scribes regularly employed a more phonetic orthography,

11445-456: Was also borrowed into Greek as the name Παφνούτιος ( Paphnutius ). That, in turn, is the source of the Russian name Пафнутий ( Pafnuty ), perhaps best known in the name of the mathematician Pafnuty Chebyshev . The Egyptian language may have the longest documented history of any language, from Old Egyptian , which appeared just before 3200 BC, to its final phases as Coptic in

11554-412: Was also used in many texts to indicate the bilabial approximant / w / . Coptologists believe that Coptic ⲃ was articulated as a voiced bilabial fricative [ β ] . In the present-day Coptic Church services, this letter is realised as / v / , but it is almost certainly a result of the pronunciation reforms instituted in the 19th century. Whereas Old Egyptian contrasts / s / and / z / ,

11663-464: Was borrowed into Arabic as ‏ قبْط ‎ ( qibṭ/qubṭ ), and from there into the languages of Europe, giving rise to words like French copte and English Copt . Coptic is today spoken liturgically in the Coptic Orthodox and Coptic Catholic Church (along with Modern Standard Arabic ). The language is spoken only in Egypt and historically has had little influence outside of

11772-574: Was enough to fill and connect them. The Egyptian Nile connected to the Sudanese Nile, which captures the Ethiopian and Equatorial headwaters during the current stages of tectonic activity in the Eastern, Central and Sudanese Rift systems. The connection of the different Niles occurred during cyclic wet periods. The Atbarah overflowed its closed basin during the wet periods that occurred about 100,000 to 120,000 years ago. The Blue Nile connected to

11881-597: Was even less understood. The ancients mistakenly believed that the Niger River represented the upper reaches of the White Nile. For example, Pliny the Elder writes that the Nile had its origins "in a mountain of lower Mauretania ", flowed above ground for "many days" distance, then went underground, reappeared as a large lake in the territories of the Masaesyli , then sank again below the desert to flow underground "for
