Same entry, according to Adler, in the Ambrosian Lexicon.
By contamination with alpha 638, presumably, the headword has been transmitted as the masculine present participle a)ei/rwn ("raising"), which has caused the gloss to be masculine also. Both should in fact be neuter. Hesychius (alpha1311) and the Etymologicum Magnum (21.43) gloss a)/eiron (or a)/iron) with a)/rrhton as well as a)qw/peuton: this would suggest derivation from the root *wer- as in e)rw=. See LSJ s.v. (web address 1). For a homonym, see alpha 637.
