Sound change

A sound change, in historical linguistics, is a change in the pronunciation of a language over time. 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 the merger of two sounds or the creation of a new sound. A sound change that affects the phonological system or the number or the distribution of its phonemes is a phonological change.
