= Lexica Segueriana 216.7 Bachmann; cf. generally Hesychius epsilon2049 (on the participle e)lhlako/tes).
The Etymologicum Magnum (325.34, 330.44) identifies this as an Attic perfect form from the verb e)lau/nw, but while compounds of the verb in this form occur in Xenophon, non-compounded forms like the one we have here are confined to Late Koine in the preserved literature. (For an instance in Procopius see under theta 141.)
