We next come to a large number of datives, ablatives, or genitives, and accusatives of verbal nouns in +tu+. This +tu+ occurs in Sanskrit in abstract nouns such as +gâtú+, going, way, etc., in Latin in _adven-tus_, etc. As these forms have been often treated, and as some of them occur frequently in later Sanskrit also, it will suffice to give one example of each:-- Dative in +tave+: +gántave+, to go, I. 46, 7. Old form in +ai+: +gántavái+, X. 95, 14. Genitive in +toḥ+: +dâtoḥ+, governed by +îśe+, VII. 4, 6. Ablative in +toḥ+: +gántoḥ+, I. 89, 9. Accusative in +tum+: +gántum+. This is the supine in _tum_ in Latin. CASES OF VERBAL NOUNS IN _TVA_. Next follow cases of verbal nouns in +tvá+, the accent being on the suffix. Datives in +tvấya+: +hatvấya+, X. 84, 2. Instrumental in +tvấ+: +hatvấ+, I. 100, 18. Older form in +tvî́+: +hatvî́+, II. 17, 6; +gatvî́+, IV. 41, 5. DATIVES IN _DHAI_ AND _DHYAI_. I have left to the end datives in +dhai+ and +dhyai+, which properly belong to the datives in +ai+, treated before, but differ from them as being datives of compound nouns. As from +máyaḥ+, delight, we have +mayaskará+, delight-making, +mayobhú+, delight-causing, and constructions like +máyo dádhe+, so from +váyas+, life, vigor, we have +váyaskṛ́t+, life-giving, and constructions like +váyo dhât+. From +dhâ+ we can frame two substantival frame, +dhâ+ and +dhi-s+, _e.g._ +puro-dhâ+, and +puro-dhis+, like +vi-dhi-s+. As an ordinary substantive, +purodhâ+ takes the feminine termination _â_, and is declined like +śivâ+. But if the verbal base remains at the end of a compound without the feminine suffix, a compound like vayodhâ would form its dative vayodhe (Grammar, § 239); and as in analogous cases we found old datives in ai, instead of _e_, e.g. +parâdai+, nothing can be said against +vayodhai+, as a Vedic dative of +vayodhâ+. The dative of +purodhi+ would be +purodhaye+, but here again, as, besides forms like dṛśaye, we met with datives, such as +ityai+, +rohishyai+, there is no difficulty in admitting an analogous dative of +purodhi+, viz., +purodhyai+.
