Phonological change
Phenomenon in phonology / From Wikipedia, the free encyclopedia
In historical linguistics, phonological change is any sound change that alters the distribution of phonemes in a language. In other words, a language develops a new system of oppositions among its phonemes. Old contrasts may disappear, new ones may emerge, or they may simply be rearranged.[1] Sound change may be an impetus for changes in the phonological structures of a language (and likewise, phonological change may sway the process of sound change).[1] One process of phonological change is rephonemicization, in which the distribution of phonemes changes by either addition of new phonemes or a reorganization of existing phonemes.[2] Mergers and splits are types of rephonemicization and are discussed further below.
