133. That is to say

That is to say, a final ए e (the most frequent case) becomes simply अ a before an initial vowel (except अ a: see 135, below), and both then remain unchanged; and a final ऐ āi, in like manner, becomes (everywhere) आ ā. Thus,

त आगताः ta āgatāḥ (te + āgatāḥ);

नगर इह nagara iha (nagare + iha);

तस्मा अददात् tasmā adadāt (tasmāi + adadāt);

स्त्रिया उक्तम् striyā uktam (striyāi + uktam).

a. The latter grammarians allow the y in such combinations to be either retained or dropped; but the uniform practice of the manuscripts, of every age, in accordance with the strict requirement of the Vedic grammars (Prātiçākhyas), is to omit the semivowel and leave the hiatus.

b. The persistence of the hiatus caused by this omission is a plain indication of the comparatively recent loss of the intervening consonantal sound.

c. Instances, however, of the avoidance of hiatus by combination of the remaining final vowel with the following initial according to the usual rules are met with in every period of the language, from the RV. down; but they are rare and of sporadic character. Compare the similar treatments of the hiatus after a lost final s, 176–7.

d. For the peculiar treatment of this combination in certain cases caused by the MS., see below, 176d.
