The headword should be w)qh/sw (error in the electronic text).
[1] The verb w)qe/w has two future stems: w)qhs- and w)s- (as if from w)/qw). See LSJ s.v. for the attestation of the various forms (web address 1). The form w)qh/somen occurs at Aristophanes, Ecclesiazusae 300 (in a lyric passage, see web address 2).
[2] The hypothetical form w)/qw is glossed by the later verb prw/qw (not in the LSJ but in Lampe). Likewise or similarly in other lexica.
[3] (Sc. because w)qe/w is a contract verb.) This comment is from ps.-Herodian, Partitiones 251.
