IPA: /əˈpɒfəni/
KK: /əˈpɑfəni/
A change in the sounds of a word that shows different grammatical forms, often used in inflection.
In English, the word 'man' changes to 'men' to show plural, which is an example of apophony.
Apophony is formed from "apo-" (meaning away from) and "phone" (from Greek "phōnē", meaning voice or sound). The term refers to a change in the form of a word that alters its sound, often used in linguistic contexts to describe vowel alternations.
Think of 'apo-' meaning 'away from' and 'phone' meaning 'sound' — this helps you remember that apophony refers to a change in sound.
