The past is the set of all events that occurred before a given point in time. The past is contrasted with and defined by the present and the future . The concept of the past is derived from the linear fashion in which human observers experience time , and is accessed through memory and recollection . In addition, human beings have recorded the past since the advent of written language. The first known use of the word "past" was in the fourteenth century; it developed as the past participle of the Middle English verb passen meaning "to pass."
57-454: In English grammar , actions are classified according to one of the following twelve verb tenses: past (past, uses of English verb forms , past perfect , or past perfect continuous ), present ( present , present continuous , present perfect , or present perfect continuous ), or future ( future , future continuous , future perfect , or future perfect continuous ). The past tense refers to actions that have already happened. For example, "she
114-422: A "grammar" in the sense that most linguists use, particularly as they are prescriptive in intent rather than descriptive . Constructed languages (also called planned languages or conlangs ) are more common in the modern-day, although still extremely uncommon compared to natural languages. Many have been designed to aid human communication (for example, naturalistic Interlingua , schematic Esperanto , and
171-419: A certain point (the train station). Alternatively, the sentence, "He ran past us at full speed," utilizes the concept of the past to describe the position of someone ("He") that is further than the speaker. The "past" is also used to define a time that is a certain number of minute before or after a particular hour , as in "We left the party at half-past twelve." People also use "past" to refer to being beyond
228-525: A discipline in Hellenism from the 3rd century BC forward with authors such as Rhyanus and Aristarchus of Samothrace . The oldest known grammar handbook is the Art of Grammar ( Τέχνη Γραμματική ), a succinct guide to speaking and writing clearly and effectively, written by the ancient Greek scholar Dionysius Thrax ( c. 170 – c. 90 BC ), a student of Aristarchus of Samothrace who founded
285-435: A discrepancy between contemporary usage and that which has been accepted, over time, as being standard or "correct". Linguists tend to view prescriptive grammar as having little justification beyond their authors' aesthetic tastes, although style guides may give useful advice about standard language employment based on descriptions of usage in contemporary writings of the same language. Linguistic prescriptions also form part of
342-418: A distinct Montenegrin standard is a matter of controversy, some treat Montenegrin as a separate standard lect, and some think that it should be considered another form of Serbian. Norwegian has two standards, Bokmål and Nynorsk , the choice between which is subject to controversy : Each Norwegian municipality can either declare one as its official language or it can remain "language neutral". Nynorsk
399-455: A particular biological age or phase of being, as in, "The boy was past the age of needing a babysitter," or, "I'm past caring about that problem." The "past" is commonly used to refer to history, either generally or with regards to specific time periods or events, as in, "Past monarchs had absolute power to determine the law in contrast to many European Kings and Queens of today." Nineteenth-century British author Charles Dickens created one of
456-584: A particular language variety involves a speaker internalizing these rules, many or most of which are acquired by observing other speakers, as opposed to intentional study or instruction . Much of this internalization occurs during early childhood; learning a language later in life usually involves more direct instruction. The term grammar can also describe the linguistic behaviour of groups of speakers and writers rather than individuals. Differences in scale are important to this meaning: for example, English grammar could describe those rules followed by every one of
513-410: A school (attached to a cathedral or monastery) that teaches Latin grammar to future priests and monks. It originally referred to a school that taught students how to read, scan, interpret, and declaim Greek and Latin poets (including Homer, Virgil, Euripides, and others). These should not be mistaken for the related, albeit distinct, modern British grammar schools. A standard language is a dialect that
570-620: A school on the Greek island of Rhodes. Dionysius Thrax's grammar book remained the primary grammar textbook for Greek schoolboys until as late as the twelfth century AD. The Romans based their grammatical writings on it and its basic format remains the basis for grammar guides in many languages even today. Latin grammar developed by following Greek models from the 1st century BC, due to the work of authors such as Orbilius Pupillus , Remmius Palaemon , Marcus Valerius Probus , Verrius Flaccus , and Aemilius Asper . The grammar of Irish originated in
627-452: A standard defining nationality or ethnicity . Recently, efforts have begun to update grammar instruction in primary and secondary education. The main focus has been to prevent the use of outdated prescriptive rules in favor of setting norms based on earlier descriptive research and to change perceptions about the relative "correctness" of prescribed standard forms in comparison to non-standard dialects. A series of metastudies have found that

By comparing the parallel columns, the reader can determine which events were contemporaneous, or how many years separated two different events. To place all the events on the same time scale, Eusebius used an Anno Mundi (A.M.) era, meaning that events were dated from the supposed beginning of the world as computed from
741-421: Is backed by 27 percent of municipalities. The main language used in primary schools, chosen by referendum within the local school district, normally follows the official language of its municipality. Standard German emerged from the standardized chancellery use of High German in the 16th and 17th centuries. Until about 1800, it was almost exclusively a written language, but now it is so widely spoken that most of

The Serbian variant of Serbo-Croatian is likewise divided; Serbia and the Republika Srpska of Bosnia and Herzegovina use their own distinct normative subvarieties, with differences in yat reflexes. The existence and codification of
855-525: Is called descriptive grammar. This kind of linguistic description contrasts with linguistic prescription , a plan to marginalize some constructions while codifying others, either absolutely or in the framework of a standard language . The word grammar often has divergent meanings when used in contexts outside linguistics. It may be used more broadly as to include orthographic conventions of written language such as spelling and punctuation, which are not typically considered as part of grammar by linguists,
912-639: Is directly based on Classical Arabic , the language of the Qur'an . The Hindustani language has two standards, Hindi and Urdu . In the United States, the Society for the Promotion of Good Grammar designated 4 March as National Grammar Day in 2008. Chronology Chronology (from Latin chronologia , from Ancient Greek χρόνος , chrónos , ' time ' ; and -λογία , -logia )
969-407: Is not on the action having been completed by the present moment, but rather on its having taken place actively over a time period before another moment in the past. The verb tense used in the sentence "She had been walking in the park regularly before I met her" is past perfect continuous because it describes an action ("walking") that was actively happening before a time when something else in the past
1026-403: Is not significant and syntax is highly significant in an analytic language. For example, Chinese and Afrikaans are highly analytic, thus meaning is very context-dependent. (Both have some inflections, and both have had more in the past; thus, they are becoming even less synthetic and more "purely" analytic over time.) Latin , which is highly synthetic , uses affixes and inflections to convey
1083-399: Is promoted above other dialects in writing, education, and, broadly speaking, in the public sphere; it contrasts with vernacular dialects , which may be the objects of study in academic, descriptive linguistics but which are rarely taught prescriptively. The standardized " first language " taught in primary education may be subject to political controversy because it may sometimes establish
1140-422: Is the science of arranging events in their order of occurrence in time . Consider, for example, the use of a timeline or sequence of events . It is also "the determination of the actual temporal sequence of past events". Chronology is a part of periodization . It is also a part of the discipline of history including earth history , the earth sciences , and study of the geologic time scale . Chronology
1197-432: Is the science of locating historical events in time. It relies mostly upon chronometry , which is also known as timekeeping, and historiography , which examines the writing of history and the use of historical methods. Radiocarbon dating estimates the age of formerly living things by measuring the proportion of carbon-14 isotope in their carbon content. Dendrochronology estimates the age of trees by correlation of

#17327660796161254-482: Is the set of rules for how a natural language is structured, as demonstrated by its speakers or writers. Grammar rules may concern the use of clauses , phrases , and words . The term may also refer to the study of such rules, a subject that includes phonology , morphology , and syntax , together with phonetics , semantics , and pragmatics . There are, broadly speaking, two different ways to study grammar: traditional grammar and theoretical grammar . Fluency in
1311-671: Is to synchronize events. By synchronizing an event it becomes possible to relate it to the current time and to compare the event to other events. Among historians, a typical need is to synchronize the reigns of kings and leaders in order to relate the history of one country or region to that of another. For example, the Chronicon of Eusebius (325 A.D.) is one of the major works of historical synchronism. This work has two sections. The first contains narrative chronicles of nine different kingdoms: Chaldean, Assyrian, Median, Lydian, Persian, Hebrew, Greek, Peloponnesian, Asian, and Roman. The second part
1368-435: Is used to describe actions that were already completed by a specific point in the past. For example, "she had walked" describes an action that took place in the past and was also completed in the past. The past perfects continuous tense refers to an action that was happening up until a particular point in the past but was completed. It is different from the past perfect tense because the emphasis of past perfect continuous verbs
1425-411: Is walking" refers to a girl who is currently walking (present tense), while "she walked" refers to a girl who was walking before now (past tense). The past continuous tense refers to actions that continued for a period of time, as in the sentence "she was walking," which describes an action that was still happening in a prior window of time to which a speaker is presently referring. The past perfect tense
1482-594: The Book of Genesis in the Hebrew Pentateuch . According to the computation Eusebius used, this occurred in 5199 B.C. The Chronicon of Eusebius was widely used in the medieval world to establish the dates and times of historical events. Subsequent chronographers, such as George Syncellus (died circa 811), analyzed and elaborated on the Chronicon by comparing with other chronologies. The last great chronographer
1539-610: The First Grammatical Treatise , but became influential only in the Renaissance and Baroque periods. In 1486, Antonio de Nebrija published Las introduciones Latinas contrapuesto el romance al Latin , and the first Spanish grammar , Gramática de la lengua castellana , in 1492. During the 16th-century Italian Renaissance , the Questione della lingua was the discussion on the status and ideal form of
1596-515: The conventions used for writing a language. It may also be used more narrowly to refer to a set of prescriptive norms only, excluding the aspects of a language's grammar which do not change or are clearly acceptable (or not) without the need for discussions. The word grammar is derived from Greek γραμματικὴ τέχνη ( grammatikḕ téchnē ), which means "art of letters", from γράμμα ( grámma ), "letter", itself from γράφειν ( gráphein ), "to draw, to write". The same Greek root also appears in
1653-639: The 12th century, compares the Hebrew language with Arabic in the Islamic grammatical tradition . Belonging to the trivium of the seven liberal arts , grammar was taught as a core discipline throughout the Middle Ages , following the influence of authors from Late Antiquity , such as Priscian . Treatment of vernaculars began gradually during the High Middle Ages , with isolated works such as
1710-429: The 16th century onward, such as Grammatica o Arte de la Lengua General de Los Indios de Los Reynos del Perú (1560), a Quechua grammar by Fray Domingo de Santo Tomás . From the latter part of the 18th century, grammar came to be understood as a subfield of the emerging discipline of modern linguistics. The Deutsche Grammatik of Jacob Grimm was first published in the 1810s. The Comparative Grammar of Franz Bopp ,
1767-459: The 3rd millennium BCE, for example. The study of the means of placing pottery and other cultural artifacts into some kind of order proceeds in two phases, classification and typology: Classification creates categories for the purposes of description, and typology seeks to identify and analyse changes that allow artifacts to be placed into sequences.

2052-446: The advent of written representations , formal rules about language usage tend to appear also, although such rules tend to describe writing conventions more accurately than conventions of speech. Formal grammars are codifications of usage which are developed by repeated documentation and observation over time. As rules are established and developed, the prescriptive concept of grammatical correctness can arise. This often produces

2394-475: The explicit teaching of grammatical parts of speech and syntax has little or no effect on the improvement of student writing quality in elementary school, middle school or high school; other methods of writing instruction had far greater positive effect, including strategy instruction, collaborative writing, summary writing, process instruction, sentence combining and inquiry projects. The preeminence of Parisian French has reigned largely unchallenged throughout

Syntax refers to the linguistic structure above the word level (for example, how sentences are formed) – though without taking into account intonation , which is the domain of phonology. Morphology, by contrast, refers to the structure at and below the word level (for example, how compound words are formed), but above

Likewise, standard Spanish is not based on the speech of Madrid but on that of educated speakers from more northern areas such as Castile and León (see Gramática de la lengua castellana ). In Argentina and Uruguay the Spanish standard

A fully revealed grammar, which describes the grammatical constructions of a particular speech type in great detail
2736-402: The level of individual sounds, which, like intonation, are in the domain of phonology. However, no clear line can be drawn between syntax and morphology. Analytic languages use syntax to convey information that is encoded by inflection in synthetic languages . In other words, word order is not significant, and morphology is highly significant in a purely synthetic language, whereas morphology
2793-701: The literary methods of synchronism used by traditional chronographers such as Eusebius, Syncellus and Scaliger, it is possible to synchronize events by archaeological or astronomical means. For example, the Eclipse of Thales , described in the first book of Herodotus can potentially be used to date the Lydian War because the eclipse took place during the middle of an important battle in that war. Likewise, various eclipses and other astronomical events described in ancient records can be used to astronomically synchronize historical events. Another method to synchronize events
2850-412: The offices of those who have previously served in an organization, group, or event such as, "past president," or, "past champions." "Past" can also refer to something or someone being at or in a position that is further than a particular point. For instance, in the sentence, "I live on Fielding Road, just past the train station," the word "past" is used to describe a location (the speaker's residence) beyond

Because Latin words are quite (though not totally) self-contained, an intelligible Latin sentence can be made from elements that are arranged almost arbitrarily. Latin has a complex affixation and simple syntax, whereas Chinese has the opposite. Prescriptive grammar is taught in primary and secondary school. The term "grammar school" historically referred to

Frameworks of grammar which seek to give a precise scientific theory of the syntactic rules of grammar and their function have been developed in theoretical linguistics . Other frameworks are based on an innate " universal grammar ", an idea developed by Noam Chomsky . In such models, the object is placed into the verb phrase. The most prominent biologically oriented theories are: Parse trees are commonly used by such frameworks to depict their rules. There are various alternative schemes for some grammar: Grammars evolve through usage . Historically, with

The first systematic grammar of Sanskrit originated in Iron Age India , with Yaska (6th century BC), Pāṇini (6th–5th century BC ) and his commentators Pingala ( c. 200 BC ), Katyayana , and Patanjali (2nd century BC). Tolkāppiyam , the earliest Tamil grammar, is mostly dated to before the 5th century AD. The Babylonians also made some early attempts at language description. Grammar appeared as
3135-540: Was Joseph Justus Scaliger (1540-1609) who reconstructed the lost Chronicon and synchronized all of ancient history in his two major works, De emendatione temporum (1583) and Thesaurus temporum (1606). Much of modern historical datings and chronology of the ancient world ultimately derives from these two works. Scaliger invented the concept of the Julian Day which is still used as the standard unified scale of time for both historians and astronomers. In addition to
3192-473: Was happening (when "I met her"). Depending on its usage in a sentence, "past" can be described using a variety of terms. Synonyms for "past" as an adjective include, "former," "bygone," "earlier," "preceding," and "previous." Synonyms for "past" as a noun include, "history, "background," "life story," and "biography." Synonyms of "past" as a preposition include, "in front of," "beyond," "by," and "in excess of." The word "past" can also be used to describe
