Likewise or similarly in other lexica: see the references at Photius mu597 Theodoridis. The headword is present passive participle, masculine nominative singular, of mue/w (cf. mu 1421). It must be quoted from somewhere -- perhaps Isaeus (cf. alpha 4590), though Latte connects the corresponding entry in Hesychius (mu1880) to Clement of Alexandria, Protrepticus 2.14, where a scholium glosses the plural of the headword (muou/menoi) with the first of the glosses used here.
