The headword is translated here as the present active participle, masculine dative plural, of e)pauxe/w (epsilon 1999), but it could also be present indicative active, third person plural. Either way, the only attestation of this form outside lexicography is Cyril of Alexandria, Quod unus sit Christus 714.13.
[1] An inaccurate quotation of Aristophanes, Birds 629 (web address 1), with scholion. The form of the verb found here would seem to be aorist indicative middle, third person singular, and it is glossed as such. In the original, the form is e)pauxh/sas ('having exulted'), an aorist active participle agreeing with a first person singular subject.
