In historical linguistics, phonological change is any sound change which alters the number or distribution of phonemes in a language.
In a typological scheme first systematized by Henry M. Hoenigswald, a historical sound law can only affect a phonological system in one of three ways:
- Conditioned merger (which Hoenigswald calls "primary split"), in which some instances of phoneme A become an existing phoneme B; the number of phonemes does not change, only their distribution.
- Phonemic split (which Hoenigswald calls "secondary split"), in which some instances of A become a new phoneme B; this is phonemic differentiation in which the number of phonemes increases.
- Unconditioned merger, in which all instances of phonemes A and B become A; this is phonemic reduction, in which the number of phonemes decreases.
This classification does not consider mere changes in pronunciation, that is, phonetic change, even chain shifts, in which neither the number nor the distribution of phonemes is affected.

Famous quotes containing the word change:
“The Anglican Church is marked by the grace and good sense of its forms, by the manly grace of its clergy. The gospel it preaches is, “By taste are ye saved.” ... It is not in ordinary a persecuting church; it is not inquisitorial, not even inquisitive, is perfectly well bred and can shut its eyes on all proper occasions. If you let it alone, it will let you alone. But its instinct is hostile to all change in politics, literature, or social arts.”
—Ralph Waldo Emerson (1803–1882)
