Pāṇini sūtras

And there is substitution of ā for the finals of mī ‘to hurt’, mi ‘to scatter and dī’to decay ‘when the affix lyap follows, as well as before those affixes which demand this substitution for the diphthong.

German In mī, mi und dī wird ā nicht nur vor solchen Suffixen, die sonst die Substitution eines Diphthongen erfordern, sondern auch vor dem Absolutivsuffix -ya substituirt. (50)
