Origin: IE [Indo-European] [1099] *tu̯ei(s)- `excite, sparkle'

Etymology: Except the isolated zero-grade ptc. σιόντα, which because of the form σείω that stands beside it must be taken as aorist, and the ablauting nominal -(σ)σόος, the whole system is built on a full grade σει(σ)-. The geminate in ep. ἐπι-σσείω, ἐ-σσείοντο shows an orig. consonantgroup, so that σείω from *tu̯eis-ō can be identified with Skt. tvéṣati (gramm.) `excite', almost only midd. `be excited, inflame, sparkle' (rejecteing Wackernagel KZ 25, 277 = Kl. Schr. 1, 221). The two languages have developped diff. in this sense, that in OInd. the middle forms have become almost completely dominating and the zero grades (e.g. ipf. 3. pl. a-tvis-anta, perf. 3. sg. ti-tviṣ-é) strongly predominate. -- Beside this stands in Iran. forms without -s- and in slightly deviating meaning, e.g. Av. ʮway-ah- n., ʮwy-ā f. `fright, danger' (IE *tu̯ei-os-, *tu̯i-ā), thus with -s- in ʮwaēšah- n. `fear'. A further member of this group is supposed in Σείριος, s. v. w. lit.; see also Mayrhofer s. tvéṣati.
