UBS Dictionary of the Greek New Testament
verb | πατέω (walk) · ἀπάτη · ἐξαπατάω · φρεναπάτης
1 This series of meanings containing the stem ἀπατ overlaps considerably in meaning with the previous series containing the stem πλαν (31.8-31.11). Both sets of terms involve deception and erroneous views. It is difficult to determine the precise implications of differences in meaning, but it may be that terms with the stem πλαν are somewhat more related to general deceptive behavior rather than primarily to misconceptions.

Abbott-Smith Greek Lexicon
ἀπατάω, -ῶ
(< ἀπάτη), [in LXX for פּתה, נשׁא hi., etc.;]
to deceive: c. acc., Ja 1:26; c. acc. pers., dat. rei, Eph 5:6; pass., I Ti 2:14 (on its infrequency in late writers, v. MM, VGT, s.v.; cf. ἐξαπατάω).†
Moulton & Milligan — Vocabulary of the Greek NT
ἀπατάω. PSI II. 152% (ii/A.p.) may show ἠπάτίων in ἃ fragmentary line at the end, with practically no context: ψεῦδος occurs a line higher up. It is surprising that this is the only citation we can make. The verb is absent from Polybius and only occurs twice in Plutarch, but is fairly frequent in LXX, and found in early Christian writers. It was evidently falling into disuse in most quarters.
