Origin: IE [Indo-European] [not] *h₃u̯is- `suppose, assume, have the opinion'

Etymology: As original forms can be considered ὀΐομαι (ῑ), ὀΐω (ῑ and ῐ), with οἴομαι, οἴω as sentence-phonetic variants. From there arose in unstressed position the esp. as parenthetic form used οἶμαι with ipf. ᾤμην (Ar.) beside ᾠόμην (Schwyzer 280 a. 679 n. 7 with J. Schmidt KZ 38, 33; diff. Wackernagel KZ 30, 315 f. = Kl. Schr. 1, 678f., Brugmann IF 29, 229ff.). From ὀϊσθῆναι, ἀν-ώϊστος appears as basic form prob. *ὀϜίσ-ι̯ομαι, from where ὀ(Ϝ)ίομαι, *ὄ(Ϝ)ι̯ομαι \> οἴομαι (cf. Chantraine Gramm. hom. 1, 29; 371f.; 405, 407). -- Further unclear. By Kretschmer KZ 31, 455 a.o. (s. Bq and W.-Hofmann s. ōmen) as *ὀϜίσ-ι̯ομαι connected with Lat. ōmen `portent' (OLat. osmen) from *ou̯is-men. As however the nouns in - men are primary verbal derivations, this etymology is possible only on condition, that the disyllabic ou̯is-, which cannot be considered as verbal root, contains a prefix o-; this can be solved by assuming *h₃u̯is-, Beekes, Devel. 58. (Diff. on ōmen Porzig IF 42, 266). Thus Brugmann l. c. assumes a prefixal *ὀ-ίσ-ι̯ομαι, to Skt. ís-yati `set in quick movement' (s. on οἶμα); prop. meaning "come on something with my thinking", semantically rather uncertain. Similarly (to IE * eis- `move violently, push', but without prefix) Krogmann KZ 63, 131. -- An uncertain supposition on original impersonal use ( ὀΐεται μοι τ 312) in Debrunner Mus. Helv. 1, 43. On the middle form Schwyzer-Debrunner 234, Balmori Emer. 1, 42 ff.
