[1] The first gloss is the present active participle, masculine nominative singular, of the verb e)piqume/w, I set my heart upon, desire; cf. epsilon 2343 and see generally LSJ s.v. The second gloss is the present middle/passive participle, masculine nominative singular, of the verb o)re/gw, I reach, grasp at, yearn for, stretch out for; cf. omicron 527 and see generally LSJ s.v.
[2] Sophocles, Electra 3 (web address 1), with the glossing of the fuller scholia there; the paidagogos points out the Mycenae palace gates to Orestes. [In her critical apparatus Adler reports that mss FV transmit, as the first two words of the quotation, not paro/nti leu/ssein but pa/restin o(ra=n (it is possible to see), and she suggests that they come 'verisim. e sch.' very probably out of a scholion. Be that as it may, this (common) phrase garbles the syntax of the original, where paro/nti is a participle dependent on e)/cesti/ soi in the preceding line.]
