A-affection or A-mutation is a phonology phenomenon in the Sindarin language through its evolution from Old Sindarin, regarding the final vowels of a word.

The phenomenon is summarized as -iCa > -eC: the final -a vowel caused the preceding i to slid into e. It also caused change of u into o.

Since all final vowels disappeared in mature Sindarin, final -a also disappeared, leaving as trace of its existence the change of the preceding vowel.

The phenomenon is seen mostly adjectives ending in -ina resulting in the common Sindarin adjectival ending -en. Other endings which possibly show A-affection are -eth (*-itta), -eb (*-ipa), -eg (*-ika)

Examples

Mithrimin perhaps did not undergo the A-affection[6]. Hence we have OS *lâmina > S. loven but M. lómin
