Vedic Metre in its Historical Development c12.s3.40

c12.s3.40

(iv) The metre everywhere supports the restoration āvṛta for ávṛta, for instance in i 133 7e (6): cf. subsection i. In derivatives of riṣ the value is optional: the negative is short in v 42 8a (9), vi 19 4d (9) and elsewhere, but long in i 63 5a (8), vi 24 9c (8), 25 2a (8) and regularly in *ariṣṭātāti* in the popular Rigveda, namely in *x 60 8e = *9e = *10d, *97 7d, *137 4b (all 3E). In *ásat* the metre agrees with the text in supporting the long vowel in v 12 4d (2T), *vii 104 12d (10) and perhaps *13c (7A).
