[1] = Synagoge sigma168; Photius, Lexicon sigma436 Theodoridis. The nominative singular headword may be a generic lexical reference, but might also be extracted from a literary source such as Euripides, who uses this form several times, e.g. Hecuba 12 (nominated by Theodoridis), Orestes 942; cf. scholia ad locc. See also sigma 898.
[2] Greek Anthology 6.252.5 (Antiphilus), using not the headword but a related adjective. The epigram recounts the gift of a quince, preserved in winter, to a noblewoman of high rank; cf. Gow and Page (vol. I, 92-93); (vol. II, 117); and further excerpts from this epigram at alpha 904, alpha 976, alpha 4212, kappa 2502, mu 934, nu 439, and pi 3074.
[3] This secondary lemma is a superlative form (masculine singular accusative or neuter singular nominative/accusative) of the adjective that has appeared in the preceding quotation (n. 2). It is evidently extracted from a literary source; the possibilities are numerous. Adler compares Anecdota Graeca (Cramer) 2.409.10 (hence Etymologicum Magnum 722.40, which similarly glosses the positive form of the adjective) and Lexicon Ambrosianum 674.
[4] This third lemma, yet another adjective related to the headword, is in the dative plural, extracted from the quotation that follows, in which context the word is neuter.
[5] Sophocles, Oedipus at Colonus 4-6, with comments from the scholia thereto.
