Starting from the inscriptional attested ὀείγην, i.e. ὀ-(Ϝ)είγην, with zero grade ὠ-(Ϝ)ίγ-νυντο (cf. ἴγνυντο ἠνοίγοντο H.; very uncertain), Fick and Bechtel (s. Lex. s. v.) want to replace the suspected ep. ἀναοίγεσκον as well as ep. ἀνέῳγε, ἀνέῳξε by *ἀν-ο-(Ϝ)είγεσκον, *ἀν-ό-(Ϝ)ειγε, *ἀν-ό-(Ϝ)ειξε, where ὀ- would be either prothetic or prefixal (cf. ὀ-κέλλω and 2. ὀ-).
Origin: IE [Indo-European] [1130] *h₃u̯eig- make give way

Not certainly explained. With Ϝιγ-, Ϝειγ- agree formally Skt. (midd.) vij-áte, vej-ate give ground, flee, to which a.o. Skt. véga- = Av. vaēγa- m. (IE *u̯óigo-s) violent movement, pressure, clash, blow (further s. εἴκω); so ὀ-(Ϝ)εί-γω, ὀ-(Ϝε)ίγ-νυμι prop. make give way, push, open (a door)? (Bechtel Lex. s.v. after Wackernagel). -- Diff., hardly to be preferred, Brugmann IF 29, 238 ff.: from *Ϝο-(ε)ιγ- to ἐπ-είγω with the same prefix as in Ϝο-φληκόσι, s. ὀφείλω. -- On the individual forms cf. Schwyzer 653 n. 10 w. lit. (also 412, 434 w. n. 3, 772), Chantraine Gramm. hom. 1. 152, 303 a. 480. S. also ἐπῳχατο. The analysis leads to *h₃u̯(e)ig-.
