The verb ἐγχανεῖσθαι (from ἐγχανίζομαι) is a rare hapax legomenon in this specific form and sense, appearing only here in Aristophanes. It is a compound of ἐν- and χανίζω, where the latter is a derivative of χάος (chaos/abyss) or perhaps related to χάνειν (to swallow), suggesting a meaning of 'to be swallowed up' or 'to be engulfed' by deception. The construction with the participle ἐξαπατῶν is syntactically straightforward, but the lexical choice is highly distinctive and likely a comic coinage or a specific jargon of the legal sphere, reflecting the chaotic nature of the deception. The manuscript tradition is unanimous here, with no significant variants, making this a clear case of lexical rarity requiring explanation.
