= Synagoge delta267, Photius delta552 Theodoridis, Etymologicum Magnum 273.53. The headword is perfect middle/passive participle, neuter nominative/accusative or masculine accusative singular, of diasmileu/w; literally 'polish off with a chisel'.
[1] The pertinence of this gloss to the headword is not immediately apparent, but it is probably a metaphorical reference to the chiseling off of shavings to bring something to a fine point. See for instance Etymologicum Magnum 718.26 s.v. sko/lopes, defining the headword ('pointed sticks') as to\ diesxisme/non kai\ a)pwcumme/non cu/lon ('wood that is split and shaved off').
[2] For examples of the figurative use of this participle, see Greek Anthology 15.38 (Cometas), referring to books, and Alexis frs. 220-1 Kock (now combined as 223 Kassel-Austin): leptoi\ diesmileume/nai te fronti/des, "subtle, refinished [philosophical] theories". Genitive plural in Hesychius delta1663 (gloss leptologhqe/ntwn); adverb id. delta1664 (gloss h)kribwme/nws); and Pollux 6.150. See also the scholia to Lucian, Bis accusatus 34, applying the headword to stylistic elegance: to\n *)attikismo/n fhsi kai\ to\ th=s le/cews a)nqhro\n kai\ diesmileume/non ("he means the Attic dialect and the flowery elegance of style").
