[1] Third person singular, present indicative middle/passive, of κολούω (kappa 1950). Evidently quoted from somewhere; similarly glossed in other lexica, and cf. the scholia to Plato, Euthydemus 305D (where the corresponding infinitive occurs).
[2] Quotation unidentifiable (Adler suggests Aelian); it employs the present active infinitive of this verb.
