Assu3 (indecl.) [Sk. sma] expletive part. also used in emphatic sense of "surely, yes, indeed" Sn 231 (according to Fausböll, but preferably with P. T. S. ed. as tayas su for tayɔ assu, cp. KhA 188); Vv 324 (assa v. l. SS) = VvA 135 (assū ti nipāta -- mattaŋ). Perhaps we ought to take this assu3 together with the foll. assu4 as a modification of ssu (see su2). Cp. āsu.
