Define historical sound change and give one short worked example.

# Historical Sound Change **Historical sound change** is a systematic alteration in the pronunciation of sounds in a language that occurs over time and affects all (or most) words containing that sound in a specific phonetic environment. These changes are regular and predictable, passed down from generation to generation of speakers. ## Worked Example: Grimm's Law (one part) **Change:** Proto-Indo-European *p > Germanic *f (in certain positions) **Environment:** Word-initially and between vowels | Proto-Indo-European | Germanic | Modern English | |---------------------|----------|----------------| | *pōds | *fōts | *foot* | | *pater | *fader | *father* | | *pisko- | *fiskaz | *fish* | **Explanation:** In the ancestral Germanic languages, all instances of the sound [p] in Proto-Indo-European regularly shifted to [f]. This is why English has "father" where Latin (which retained the original *p) has "pater," and why English "fish" corresponds to Latin "piscis." This change was **systematic** (affected all relevant words), **regular** (no exceptions in this environment), and **unconscious** (speakers didn't deliberately decide to make the change).
