Derksen gives it, but Vasmer and Černyx not. — Игорь Телкачь 12:50, 3 March 2015 (UTC)

Natively Slavic???
In Russian it's the only prefix that takes the stress in all perfective verbs it appears in (analogically to German aus-, in the forms where the latter acts as a prefix and not more like a part of a phrasal verb). It's pretty obvious that it must've been borrowed from Germanic ūt. 195.187.108.4 15:39, 16 February 2022 (UTC)
 * The stress attraction is not enough to deduce borrowing: cf. 🇨🇬, 🇨🇬 (both dominating the ictus). Безименен (talk) 21:41, 16 February 2022 (UTC)
 * I see. Although it's hard to compare *vy- with *pa-, because the latter has a prepositional variant (*po) and the former doesn't. Not enough data to compare. 195.187.108.4 17:41, 4 April 2022 (UTC)
