A yer is either of two letters in Cyrillic alphabets , ъ (ѥръ, jerŭ ) and ь (ѥрь, jerĭ ). The Glagolitic alphabet used, as respective counterparts, the letters (Ⱏ) and (Ⱐ). They originally represented phonemically the "ultra-short" vowels in Slavic languages , including Old Church Slavonic , and are collectively known as the yers.
50-413: In all modern Slavic languages, they either evolved into various "full" vowels or disappeared, in some cases causing the palatalization of adjacent consonants. The only Slavic language that still uses "ъ" as a vowel sign (pronounced /ɤ/) is Bulgarian, but in many cases, it corresponds to an earlier ѫ (big yus) , originally pronounced /õ/, used in pre 1945 Bulgarian orthography . Many languages that use
100-592: A change operates unconditionally (in all environments), the context in which it applies must be specified: For example: Here is a second example: The symbol "#" stands for a word boundary (initial or final) and so the notation "/__#" means "word-finally", and "/#__" means "word-initially": That can be simplified to in which P stands for any plosive . In historical linguistics , a number of traditional terms designate types of phonetic change, either by nature or result. A number of such types are often (or usually) sporadic, that is, more or less accidents that happen to
150-629: A common ancestor and synchronic variation . Dialectologists are concerned with grammatical features that correspond to regional areas. Thus, they are usually dealing with populations living in specific locales for generations without moving, but also with immigrant groups bringing their languages to new settlements. Immigrant groups often bring their linguistic practices to new settlements, leading to distinct linguistic varieties within those communities. Dialectologists analyze these immigrant dialects to understand how languages develop and diversify in response to migration and cultural interactions. Phonology
200-435: A former yer . For example (OR = Old Russian; R = Russian): Sound change In historical linguistics , a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound (or, more generally, one phonetic feature value) by a different one (called phonetic change ) or a more general change to the speech sounds that exist ( phonological change ), such as
250-415: A given time, usually the present, but a synchronic analysis of a historical language form is also possible. It may be distinguished from diachronic, which regards a phenomenon in terms of developments through time. Diachronic analysis is the main concern of historical linguistics. However, most other branches of linguistics are concerned with some form of synchronic analysis. The study of language change offers
300-413: A hybrid known as phono-semantic matching . In languages with a long and detailed history, etymology makes use of philology , the study of how words change from culture to culture over time. Etymologists also apply the methods of comparative linguistics to reconstruct information about languages that are too old for any direct information (such as writing) to be known. By analysis of related languages by
350-510: A part of a more broadly-conceived discipline of historical linguistics. For the Indo-European languages, comparative study is now a highly specialized field. Some scholars have undertaken studies attempting to establish super-families, linking, for example, Indo-European, Uralic, and other families into Nostratic . These attempts have not met with wide acceptance. The information necessary to establish relatedness becomes less available as
400-528: A previous sound change causes X,Y > Y (features X and Y merge as Y), a new one cannot affect only an original X. Sound change ignores grammar : A sound change can have only phonological constraints, like X > Z in unstressed syllables . For example, it cannot affect only adjectives . The only exception is that a sound change may recognise word boundaries, even when they are unindicated by prosodic clues. Also, sound changes may be regularized in inflectional paradigms (such as verbal inflection), when it
450-409: A specific form. Others affect a whole phonological system. Sound changes that affect a whole phonological system are also classified according to how they affect the overall shape of the system; see phonological change . Historical linguistics Historical linguistics , also known as diachronic linguistics , is the scientific study of how languages change over time. It seeks to understand
500-476: A valuable insight into the state of linguistic representation, and because all synchronic forms are the result of historically evolving diachronic changes, the ability to explain linguistic constructions necessitates a focus on diachronic processes. Initially, all of modern linguistics was historical in orientation. Even the study of modern dialects involved looking at their origins. Ferdinand de Saussure 's distinction between synchronic and diachronic linguistics
550-428: Is aspirated , but the p in spin is not. In English these two sounds are used in complementary distribution and are not used to differentiate words so they are considered allophones of the same phoneme . In some other languages like Thai and Quechua , the same difference of aspiration or non-aspiration differentiates words and so the two sounds, or phones , are considered to be distinct phonemes. In addition to

#1732791007738600-437: Is a branch of historical linguistics that is concerned with comparing languages in order to establish their historical relatedness. Languages may be related by convergence through borrowing or by genetic descent, thus languages can change and are also able to cross-relate. Genetic relatedness implies a common origin among languages. Comparative linguists construct language families , reconstruct proto-languages , and analyze
650-401: Is a sub-field of linguistics which studies the sound system of a specific language or set of languages. Whereas phonetics is about the physical production and perception of the sounds of speech, phonology describes the way sounds function within a given language or across languages. Phonology studies when sounds are or are not treated as distinct within a language. For example, the p in pin
700-512: Is available, such as Uralic and Austronesian . Dialectology is the scientific study of linguistic dialect , the varieties of a language that are characteristic of particular groups, based primarily on geographic distribution and their associated features. This is in contrast to variations based on social factors, which are studied in sociolinguistics , or variations based on time, which are studied in historical linguistics. Dialectology treats such topics as divergence of two local dialects from
750-473: Is expected to apply mechanically whenever its structural conditions are met, irrespective of any non-phonological factors like the meaning of the words that are affected. Apparent exceptions to regular change can occur because of dialect borrowing, grammatical analogy, or other causes known and unknown, and some changes are described as "sporadic" and so they affect only one or a few particular words, without any apparent regularity. The Neogrammarian linguists of
800-596: Is frequently used as a substitute for ъ without any ambiguity arising. In Old Church Slavonic , the yer was used to indicate the so-called "reduced vowel": ъ = *[ŭ] , ь = *[ĭ] in the conventional transcription. They stemmed from the Proto-Balto-Slavic and Proto-Indo-European short */u/ and */i/ (compare Latin angulus and Old Church Slavonic ѫгълъ , ǫgŭlŭ < Early Proto-Slavic *angulu < Proto-Balto-Slavic *ángulas < Proto-Indo-European *h₂éngulos ). In all West Slavic languages ,
850-532: Is fundamental to the present day organization of the discipline. Primacy is accorded to synchronic linguistics, and diachronic linguistics is defined as the study of successive synchronic stages. Saussure's clear demarcation, however, has had both defenders and critics. In practice, a purely-synchronic linguistics is not possible for any period before the invention of the gramophone , as written records always lag behind speech in reflecting linguistic developments. Written records are difficult to date accurately before
900-417: Is inevitable : All languages vary from place to place and time to time, and neither writing nor media prevents that change. A statement of the form is to be read as "Sound A changes into (or is replaced by, is reflected as, etc.) sound B". Therefore, A belongs to an older stage of the language in question, and B belongs to a more recent stage. The symbol ">" can be reversed, B < A, which also means that
950-441: Is linguistic change in progress. Synchronic and diachronic approaches can reach quite different conclusions. For example, a Germanic strong verb (e.g. English sing ↔ sang ↔ sung ) is irregular when it is viewed synchronically: the native speaker's brain processes them as learned forms, but the derived forms of regular verbs are processed quite differently, by the application of productive rules (for example, adding -ed to
1000-477: Is no longer phonological but morphological in nature. Sound change is exceptionless : If a sound change can happen at a place, it will affect all sounds that meet the criteria for change. Apparent exceptions are possible because of analogy and other regularization processes, another sound change, or an unrecognized conditioning factor. That is the traditional view expressed by the Neogrammarians. In
1050-496: Is the study of patterns of word-formation within a language. It attempts to formulate rules that model the knowledge of speakers. In the context of historical linguistics, formal means of expression change over time. Words as units in the lexicon are the subject matter of lexicology . Along with clitics , words are generally accepted to be the smallest units of syntax ; however, it is clear in most languages that words may be related to one another by rules. These rules are understood by

Research on sound change is usually conducted under the working assumption that it is regular , which means that it
1150-400: The comparative method and the method of internal reconstruction . Less-standard techniques, such as mass lexical comparison , are used by some linguists to overcome the limitations of the comparative method, but most linguists regard them as unreliable. The findings of historical linguistics are often used as a basis for hypotheses about the groupings and movements of peoples, particularly in

In that way, word roots that can be traced all the way back to the origin of, for instance, the Indo-European language family have been found. Although originating in the philological tradition, much current etymological research is done in language families for which little or no early documentation
1250-475: The origin of language ) studies Lamarckian acquired characteristics of languages. This perspective explores how languages adapt and change over time in response to cultural, societal, and environmental factors. Language evolution within the framework of historical linguistics is akin to Lamarckism in the sense that linguistic traits acquired during an individual's lifetime can potentially influence subsequent generations of speakers. Historical linguists often use
1300-422: The (more recent) B derives from the (older) A": The two sides of such a statement indicate only the start and the end of the change, but additional intermediate stages may have occurred. The example above is actually a compressed account of a sequence of changes: * [t] first changed to [θ] (like the initial consonant of English thin ), which has since yielded [f] and can be represented more fully: Unless
1350-467: The 19th century introduced the term sound law to refer to rules of regular change, perhaps in imitation of the laws of physics, and the term "law" is still used in referring to specific sound rules that are named after their authors like Grimm's law , Grassmann's law , etc. Real-world sound laws often admit exceptions, but the expectation of their regularity or absence of exceptions is of great heuristic value by allowing historical linguists to define

The back yer ( Ъ , ъ , italics Ъ , ъ ) of the Cyrillic script , also spelled jer or er , is known as the hard sign in the modern Russian and Rusyn alphabets and as ер голям (er golyam, "big er") in the Bulgarian alphabet .

However, a diachronic analysis shows that the strong verb is the remnant of a fully regular system of internal vowel changes, in this case the Indo-European ablaut ; historical linguistics seldom uses the category " irregular verb ". The principal tools of research in diachronic linguistics are

Often, dating must rely on contextual historical evidence such as inscriptions, or modern technology, such as carbon dating , can be used to ascertain dates of varying accuracy. Also, the work of sociolinguists on linguistic variation has shown synchronic states are not uniform: the speech habits of older and younger speakers differ in ways that point to language change.

Its companion, the front yer ( Ь , ь , italics Ь , ь ), now known as the soft sign in Russian, Belarusian and Ukrainian , and as ер малък (er malak, "small er") in Bulgarian, originally also represented a reduced vowel, more frontal than the ъ. Today, it marks the palatalization of consonants in all of

Sound changes can be environmentally conditioned if the change occurs in only some sound environments , and not others. The term "sound change" refers to diachronic changes, which occur in a language's sound system. On the other hand, " alternation " refers to changes that happen synchronically (within

Principles of phonology have also been applied to the analysis of sign languages , but the phonological units do not consist of sounds. The principles of phonological analysis can be applied independently of modality because they are designed to serve as general analytical tools, not language-specific ones. Morphology

This field is grounded in the Uniformitarian Principle , which posits that

Each sound change is limited in space and time and so it functions in a limited area (within certain dialects ) and for a limited period of time. For those and other reasons, the term "sound law" has been criticized for implying a universality that is unrealistic for sound change. A sound change that affects the phonological system or

The following statements are used as heuristics in formulating sound changes as understood within the Neogrammarian model.

However, ъ is only necessary for the purposes of disambiguation between a consonant and an iotated vowel in situations when palatalization should not occur, as by default it would. It is therefore rarely used. As it is not necessary to specify palatalization under those circumstances, the much more common ь

2100-660: The past decades, however, it has been shown that sound change does not necessarily affect all possible words. However, when a sound change is initiated, it often eventually expands to the whole lexicon . For example, the Spanish fronting of the Vulgar Latin [g] ( voiced velar stop ) before [i e ɛ] seems to have reached every possible word. By contrast, the voicing of word-initial Latin [k] to [g] occurred in colaphus > golpe and cattus > gato but not in canna > caña . See also lexical diffusion . Sound change
2150-472: The prehistoric period. In practice, however, it is often unclear how to integrate the linguistic evidence with the archaeological or genetic evidence. For example, there are numerous theories concerning the homeland and early movements of the Proto-Indo-Europeans , each with its own interpretation of the archaeological record. Comparative linguistics , originally comparative philology ,
2200-413: The processes of language change observed today were also at work in the past, unless there is clear evidence to suggest otherwise. Historical linguists aim to describe and explain changes in individual languages, explore the history of speech communities, and study the origins and meanings of words ( etymology ). Modern historical linguistics dates to the late 18th century, having originally grown out of

Syntax is the study of the principles and rules for constructing sentences in natural languages . Syntax directly concerns the rules and principles that govern sentence structure in individual languages. Researchers attempt to describe languages in terms of these rules. Many historical linguistics attempt to compare changes in sentence between related languages, or find universal grammar rules that natural languages follow regardless of when and where they are spoken. In terms of evolutionary theory, historical linguistics (as opposed to research into
2300-409: The strong yers evolved into various sounds that varied across different languages. To determine whether a yer is strong or weak, one must break the continuous flow of speech into individual words, or prosodic units (phrases with only one stressed syllable, typically including a preposition or other clitic words). The rule for determining weak and strong yers is as follows: In Russian, for example,
2350-415: The time increases. The time-depth of linguistic methods is limited due to chance word resemblances and variations between language groups, but a limit of around 10,000 years is often assumed. Several methods are used to date proto-languages, but the process is generally difficult and its results are inherently approximate. In linguistics, a synchronic analysis is one that views linguistic phenomena only at
2400-483: The yer either disappeared or changed to /e/ in strong positions, and in South Slavic languages , the strong yer reflexes differ widely, according to dialect. In Common Slavic , the yers were normal short vowels /u/ and /i/. Havlik's law caused them, in certain positions, to be pronounced very weakly, perhaps as ultrashort vowels, and to lose the ability to take word accent. The weak yers were later dropped, and
2450-682: The yers evolved as follows: Simply put, in a string of Old Russian syllables, each of which has a reduced vowel, the reduced vowels are, in Modern Russian, alternately given their full voicing or drop: the last yer in the sequence drops. There are some exceptions to the rule, usually considered to be the result of analogy with other words or other inflected forms of the same word, with a different original pattern of reduced vowels. Modern Russian inflection is, therefore, complicated by so-called "transitive" (lit. беглые [ˈbʲeɡlɨjə] "fugitive" or "fleeting") vowels, which appear and disappear in place of
