comment Why A is pronounced differently in “opacity” and “opaque”
This is not the same process as apophony. Apophony is where a phonemic alternation indicates a grammatical difference, as in "sing" vs. "sang" vs. "sung". The changes in the words you indicated are secondary changes that stem from the fact that (a) certain morphemes move the stress onto them or onto a preceding syllable; (b) English vowels are reduced in unstressed syllables. Similar changes occur in Russian and (to some extent) Egyptian Arabic, among other languages.
