Headword and gloss could be either second person singulars, future, of verbs or nominative/accusative plurals of nouns. The former is to be preferred because of the parallel with a scholion on Apollonius Rhodius, Argonautica 3.983, where the aorist subjunctive fhlw/sh|s occurs (web address 1). Other lexica have same or similar glossing.
