The headword is third person singular, aorist middle, of e(/nnumi; cf. eta 591, eta 592. It is presumably extracted from the quotation given, though it does also occur in (e.g.) Homer, Iliad 7.207 and 10.334.
[1] Greek Anthology 6.266.3 (Hegesippus), Hagelocheia dedicates a figure of Artemis to the goddess; cf. Gow and Page (vol. I, 104), (vol. II, 300-301), and another extract from this epigram at lambda 766. As Gow and Page note (vol. II, 300), here the Suda's gloss appears to misinterpret the headword, given the context of e(/ssato in the rest of the epigram. It could indeed mean to drape garments around, as the gloss would indicate. But this sense is also quite improbable, given that the dedication evidently takes place outdoors, at a crossroads; cf. Gow and Page, (vol. I, 104) and Paton (442-443). Moreover, in the first line of the epigram Hagelocheia is bringing "this Artemis" to dedicate after the girl saw the goddess in a vision; it is apparently some kind of figure, a picture, a statuette, or some representational object and not an article of clothing. As Gow and Page further observe (vol. II, 300), the headword is also the aorist middle of i(/zw, which means to "set down" or "erect", and this interpretation of the headword does align with the epigram's broader context.
