This form of the headword, the nominative singular masculine/feminine, is unattested outside lexicography; however, plural forms occur frequently in hexameter poetry, in the formula xei=res a)/aptoi or xei=ras a)a/ptous (usually interpreted as 'irresistable hands'); e.g. Homer, Iliad 8.450 (web address 1).
[1] The etymological comments that follow occur only in mss G (= Parisinus 2623) and T (= Vaticanus 881); cf. Herodianus 3.2.30.
[2] This etymology, alpha-privative + a(/ptomai ('touch'), is the one most commonly accepted nowadays. See LSJ s.v. (web address 2) and Schwyzer, DGE. Yet there is reason for doubt, and the correct Homeric form (attested already by Aristophanes of Byzantium) may actually be a)ept-. See Chantraine s.v. a)/aptos.

The headword is aorist active infinitive, glossed with four others. The entry = Photius, Lexicon alpha9 Theodoridis, and similar material can be found in Synagoge (Codex B) alpha4 (Lexica Segueriana 3.5-7). Compare also Etymologicum Gudianum 1.8. This particular form is unattested outside lexicography, though it appears as an entry in Apollonius Sophistes, Homeric Lexicon 2.5, and is presumably related to such Homeric forms as we find at alpha 7.
[1] This meaning is unattested for the verb a)a/w (LSJ entry at web address 1).
[2] In that one loses consciousness and control in sleep, as in Homer Odyssey 10.68 (web address 2).

The headword is the third person plural, aorist indicative active, of a)bake/w. This form is found only in Homer, Odyssey 4.249 (web address 1), and the many lexicographical notices generated by it. Of those the most similar to this entry are Photius, Lexicon alpha22 Theodoridis, and Etymologicum Magnum 2.30-31. Compare also Apollonius Sophistes, Homeric Lexicon 2.16; Hesychius alpha54. The glosses offered here and elsewhere probably represent semantic extrapolation from the Homeric context: When Odysseus comes in disguise to Troy, Helen knows who he is but the rest of the people in Troy a)ba/khsan. The translation of the headword, on the other hand, reflects the verb's probable etymological connection with the verb ba/zw 'speak', and the adjective a)bakh/s ('speechless', 'tranquil'). Cf. Chantraine s.v. a)bakh/s, a connection that is sometimes mentioned as a possibility in the ancient scholarship.

For the headword see LSJ s.v. a)/bale (web address 1). The entry = Photius, Lexicon alpha26 Theodoridis, and, with the exception of the repetition of the headword within the entry (see note 2), also Synagoge alpha1 (Lexica Segueriana 3.10), Hesychius (s.v. a)/ ba/le, alpha60) and Apollonius Sophistes, Homeric Lexicon 2.15. The word does not occur in the extant text of Homer, but there are other literary attestations including Callimachus fr. 619 Pfeiffer, and Greek Anthology 7.583.1 (Agathias Scholasticus).
cf. generally alpha 14.

[2] Apparently the beginning of a quotation, perhaps from one of the works mentioned above; otherwise the repetition of the headword is hard to explain. See Theodoridis' note.
