UBS Dictionary of the Greek New Testament
noun, f. | -ας | μαίνομαι
30.24 · Think · To Think, Thought
to not be in one’s right mind, to be insane, to be mad, to be out of one’s mind, insanity, madness to think or reason in a completely irrational manner In some languages μανία is best rendered by an idiomatic expression, for example, ‘thoughts that never return,’ ‘distorted thoughts,’ ‘senseless thoughts,’ or ‘thoughts that cannot be understood.’
1 It is possible that there are some significant differences in meaning between the set μαίνομαι / μανία and the set παραφρονέω / παραφρονία, but the difference is likely to be more connotative than denotative, as, for example, the distinction in English between crazy and insane.

Moulton & Milligan — Vocabulary of the Greek NT
μανια Mapua τὸν ᾿Αχιλλέα προβαλόμενον ἑαυτὸν eis ἐξηγίητείαν) ἀπόντων | de vita εἰ morte 5, and see P Leid W¥it (ii/iii A.D.) ἡμῶν, ‘‘ we have learned that Achilles in our absence put himself forward for the office of exegetes’’ (Edd.), P Oxy VII. 10678 (iii/A.D.) μάθε οὖν ὅτι ἀλλοτρίαν γυναῖκαν ἐκληρονόμησεν αὐτόν, ““Κπονν then that a strange woman is made | his heir” (Ed.), ὁ. XIV. 1671?° (iii/A.D.) γράψον οὖν ἵνα τὴν διαταγὴν μάθω, ‘write therefore, that I may learn the order” (Edd.), P Tebt 11. 4174 (iii/A.D.) μάθε tod Μώρου, “find out from Morus.” The form ἐμάθαμεν (cf. Moulton Proleg. p. 51) is found in P Oxy VII. 103275 (a.p. 162). On the difficult 1 Tim 513, where μανθάνω is practically pass. of διδάσκω, see Moulton Proleg. p. 229: cf. Field Notes, p. 210. With 2 Tim 37 we may compare Epict. i. 29. 35 ἤθελον ἔτι μανθάνειν, “1 would fain go on learning.’”’ MGr μαθαίνω has lost the nasal: the aor. stem has prevailed over the present, but cf. also the disappearance of the v from the MGr ἄθρωπος.
