244. Vowel-lengthening

Vowel-lengthening.

Vowel-lengthening concerns especially i and u, since lengthening of a is in part (except where in evident analogy with that of i and u) indistinguishable from its increment, and ṛ is made long only in certain plural cases of stems in ṛ (or ar: 369 ff.). Lengthening is a much more irregular and sporadic change than increment, and its cases will in general be left to be pointed out in connection with the processes of inflection and derivation: a few only will be mentioned here.
