[1] Headword and gloss again under alpha 1417. The gloss is a present participle, feminine nominative singular. The headword itself is possibly one too, or intended to be, though we might have expected a)loiw=sa; perhaps, therefore, an adjective.
[2] Likewise or similarly in other lexica; references at Photius alpha1021 Theodoridis. (This infinitive also appears under rho 228.)
