The headword, dative plural of the adjective a)/texnos (for its range of related senses see LSJ s.v.), is evidently quoted from somewhere; extant possibilities are late and numerous.
[1] Other lexica (Synagoge alpha1052, (Codex B) alpha2343; Photius alpha3083) have "guileless" (a)panou/rgois), here, surely correctly. Adler maintains the unanimous reading of the Suda mss: panou/rgois, "guileful".
[2] Having begun with a definition of an adjective, the entry now turns to two cognate adverbial forms, which have different meanings according to the accent (LSJ entries at web addresses 1 & 2). Most of the entry consists of quotations, often overlapping, of various lexicographers, scholiasts, and grammarians of late antiquity. Only citations of significance are noted here.
[3] Damascius, Life of Isidore fr. 125 Zintzen (75 Asmus. See generally Athanassiadi for text and commentary). The "she" in question is the 5th century CE Neoplatonic philosopher Aidesia/Aedesia of Alexandria, student of Proclus at Athens, daughter, wife, and mother of Neoplatonic philosophers: see alphaiota 79.
[4] cf. tau 441 (and Harpokration and Photius s.v.).
[5] Plato, Euthyphro 3A, supplies only the word "utterly," the synonyms being the lexicographer's.
[6] Quotation unidentifiable, though one (proverbial-sounding) element of it, "the happiness of Aristotle", is used in fr.4 (preserved by Eusebius) of the C2-CE Platonist philosopher Atticus [OCD(4) p.204].
[7] Aristophanes, Clouds 425, where however, the text has the first person. Strepsiades says that he would not discuss anything with any other gods than the ones Socrates has just named, Emptiness and Clouds and Tongue.
[8] Homer, Odyssey 8.296-97: Hephaestus lays a snare for the adulterous Ares and Aphrodite.
