Kâshinâth Trimbak Telang, Sacred Books of the East - Volume VIII (1882)
“ Adverting specially to the language as distinguished from the style of the Gîtâ, we find such words as Anta, Bhâshâ, Brahman, some of which are collected in the Sanskrit Index in this volume, which have gone out of use in the classical literature in the significations they respectively bear in the Gîtâ. The word 'ha,' which occurs once, is worthy of special note. It is the equivalent of 'gha,' which occurs in the Vedic Samhitâs. In the form 'ha' it occurs in the Brâhmanas. But it never occurs, I think, in what is properly called the classical literature. ”
