The headword as transmitted -- but see n.1 below -- is the present middle/passive participle, masculine (and neuter) dative plural, of the verb o)rguio/omai. See generally LSJ s.v.; cf. the perfect form, with identical glosses, at omega 164; and cognates at omicron 521 and omicron 523. [In her critical apparatus, Adler notes that ms S transmitted the headword as o)rguwme/nois and ms M (after correction) gave the perfect tense w)rguiwme/nois.]
[1] The first gloss is the perfect middle/passive participle, masculine (and neuter) dative plural, of the verb e)ktei/nw, I stretch out; see LSJ s.v. It is attested in, for example, the Aristotelian Physiognomonics, at 813a11 (almost certainly not due to Aristotle: Vogt, pp. 187-97 and Brennan, pp. 203). The headword and the first gloss, both in the accusative plural, appear in Lycophron, Alexandra 26, and its corresponding scholion, respectively. A metaphorical sense of the headword, the second gloss is the present active participle, masculine (and neuter) dative plural of the verb e)piqume/w, I desire, set my heart upon; see LSJ s.v. and cf. Etymologicum Magnum 629.46-56 (Kallierges). Other lexica provide this same gloss for alternative spellings of the headword: see the references at Photius omicron447 Theodoridis, where in fact the editor follows Dobree and Cobet in supposing that the headword has been corrupted from o)rignwme/nois. (If that is so, it might [DW] be quoted from Josephus, Jewish Antiquities 17.153.)
