The headword is the present active participle, masculine nominative plural, of the epic/poetic verb ti/w, I honor (as toward the gods); cf. tau 649, tau 669, and see generally LSJ s.v. It is presumably extracted from somewhere, very probably -- see next note -- from one of the instances (C4 CE) in the poetry of Gregory of Nazianzus: Poems about himself (Carmina de se ipso) PG 37.1365; Poems which relate to others (Carmina quae spectant ad alios) PG 37.1491 and PG 37.1539. (Another in Quintus of Smyrna, Posthomerica 4.96.)
[1] The gloss is the same form as the lemma, but from the contract verb tima/w, I honor; see generally LSJ s.v. The headword is identically glossed in the Synagoge (tau186), Photius' Lexicon (tau316 Theodoridis), and -- missed by Theodoridis -- the Lexicon in orationes Gregorii Nazianzeni (tau66). By way of comparison Adler cites a scholion (= D scholia) to Homer, Iliad 8.161 (web address 1), where third person plural imperfect ti/on is glossed with e)ti/mwn.
