The headword -- perfect passive, third person singular, of diaqwke/w -- must be quoted from somewhere but is unattested outside lexica.
[1] This gloss does not occur in the corresponding entry in Hesychius and Photius. It may represent a mistaken association on the part of the lexicographer with qake/w (epic, Ionic and Doric: qwke/w; cf. theta 3, theta 425) meaning 'sit', but compounds of this verb with the prefix dia- are otherwise unattested.
