[1] The headword is second person singular imperative of a)qre/w (alpha 752). It must be quoted from somewhere; there are numerous possibilities. Same glossing in Photius and other lexica.
[2] Present participle, masculine nominative plural, with the same glossing in the Etymologicum Gudianum (interpreting the participle as from a desiderative verb a)qrei/w). Again, it must be quoted from somewhere, but is not independently attested.
