I have connected this adverb with Skt. atha,having the same meaning, and with OHG. unti, anti, enti =OE., Eng. and,Germ, und(cf. BSL.,41, 184 and also my Lexique (étymologiqbe des dialectes tokhariens),20);the Tocharian form agrees with Skt. athain its root-vocalism:both Sanskrit and Tocharian show the weak grade, IE. *nth-.This etymology, however, leaves the w-suffix of Toch. B. entweunexplained:for -weI have only assumed a secondary origin. At present this view seems no more plausible to me:several extended forms of Skt. atharender imperative a primary origin. Skt. athais attested with following him(“yes, well ”, in dialogue), with following ajri(“nevertheless ”), and with following uand vā.Skt. atha + umeans “afterwards, then, and, even ”, and Skt. atha+vā“or, or also, or even, etc.”Both Skt. atha + uand atha+ vāmay be the formal equivalents of Toch. B. entwe,but an original *-vē-extension is more probable for the Tocharian form, since the final of the Indo-European words is dropped in this language.
