Semantic change (also semantic shift, semantic progression, semantic development, or semantic drift) is a form of language change regarding the evolution of word usage—usually to the point that the modern meaning is radically different from the original usage.
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 ...
Diachronic or historical lexicology is devoted to the evolution of words and word-formation over time. It investigates the origins of a word and the ways in which its structure, meaning, and usage have since changed. [9] Synchronic or descriptive lexicology examines the words of a language within a certain time frame. This could be a period ...
Words' meanings may also change in terms of the breadth of their semantic domain. Narrowing a word limits its alternative meanings, whereas broadening associates new meanings with it. For example, "hound" (Old English hund) once referred to any dog, whereas in modern English it denotes only a particular type of dog. On the other hand, the word ...
Cyclic drift is the mechanism of long-term evolution that changes the functional characteristics of a language over time, such as the reversible drifts from SOV word order to SVO and from synthetic inflection to analytic observable as typological parameters in the syntax of language families and of areal groupings of languages open to investigation over long periods of time.
Linguistics is the scientific study of language. [1] [2] [3] The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language), and pragmatics (how the context of use contributes to ...
The highly diverse Nilo-Saharan languages, first proposed as a family by Joseph Greenberg in 1963 might have originated in the Upper Paleolithic. [1] Given the presence of a tripartite number system in modern Nilo-Saharan languages, linguist N.A. Blench inferred a noun classifier in the proto-language, distributed based on water courses in the Sahara during the "wet period" of the Neolithic ...
According to this hypothesis, languages evolved as several lineages independent of one another. [16] Modern investigation about creole languages demonstrated that with an appropriate linguistic input or pidgin, children develop a language with stable and defined grammar in one generation. [17] Creole languages descend from pidgins.
