The headword (which occurs in the first quotation given in the masculine accusative singular) is an adjective in the masculine nominative singular; see generally LSJ s.v.
[1] The gloss is the same grammatical form as the headword. The headword is similarly glossed by Orion [Author, Myth], Etymologicum 122.5; Etymologicum Magnum 621.6 (Kallierges), and ps.-Zonaras 1438.26. The masculine (and neuter) dative singular form of the headword occurs at Homer, Iliad 4.518 (web address 1); cf. Hesychius omicron491, and Apollonius' Homeric Lexicon 120.1. Adler also cites the Lexicon de Spiritu, L.C. Valckenaer, ed.
[2] Greek Anthology 6.65.5-6, attributed to Paul the Silentiary (d. ca. 580 CE); OCD(4) s.v. and PLRE, s.v. Paulus (21). The parenthetical remark, identifying the stone as volcanic pumice, is inserted into the epigram by the Suda; cf. kappa 1670.
[3] The adjective o)kruo/essa, probably extracted from the quotation given, is the feminine nominative (and vocative) singular form of o)kruo/eis, -essa, -en; see LSJ s.v. This adjective and the first of the following glosses -- frikth/ (feminine nominative/vocative singular of the adjective frikto/s, -h/, -o/n) -- are also given by the scholia to Homer, Iliad 5.740 (web address 2) and by ps.-Zonaras 1440.1. The genitive singular forms of the adjective and its gloss, o)kruoe/sshs and frikth=s, respectively, are found in the scholia to Homer, Iliad 6.344 (web address 3); cf. Hesychius omicron494-495. Here Adler also cites Lexicon Ambrosianum 122 and Valckenaer's Lexicon de Spiritu. [In her critical apparatus Adler reports that mss TM transmit o)krio/essa.]
[4] Greek Anthology 7.67.3-4 (Leonidas of Tarentum); epitaph of Diogenes, addressed to Charon [Author, Myth]; already in full at beta 114 and slightly abridged at alpha 3638; cf. Gow and Page (vol. I, 126); (vol. II, 367-368); and further excerpts from this epigram at epsilon 2061, epsilon 3944, and pi 2073. Diogenes the Cynic (the Dog; 412/403-324/321 BCE; from the city of Sinope, in Asia Minor, present-day Sinop in Turkey; Barrington Atlas map 87 grid A2) flouted social norms and espoused a simple, natural style of life; see generally OCD(4) s.v. Diogenes(2), and cf. delta 1141, delta 1143, delta 1144. On Charon, ferryman of the dead to Hades, see chi 135. [In her critical apparatus Adler reports that mss GTM read o)krio/essa within the quoted epitaph.]
