The headword (quoted from Aristophanes: see below) is nominative feminine singular of the adjective li/spos. (The nominative masculine singular is not attested.)
Except for the last sentence (on which see n. 6 below), the entry conforms, with a significant omission, to the scholia to Aristophanes, Frogs 826. For many of the definitions proffered here there is no support outside these assertions. For a discussion of the original passage in Frogs, and for the cutting in two of astragaloi, see lambda 604 and the reference to Plato there.
[1] This word is not found in the surviving texts of Apollonius Dyscolus.
[2] The scholiast assigns this definition to Callistratus, but no such reference is known. The Commentary on Frogs 826b defines our headword simply as 'very small', leptota/th .
[3] The haunches were called li/sfoi in Attic Greek according to Etym. Gen. 121. But there was confusion over this otherwise unattested word, for Tzetzes believed it the Attic form of our li/spos (on Hesiod, Works and Days 156) and Moeris took it as Attic for 'without buttocks' (p.245P.).
[4] See alpha 4250, astragalos.
[5] This word is not attested elsewhere in Greek, and the reading in the scholia strufnou\s is inappropriate in meaning, 'harsh'.
[6] See lambda 604 for the use of this idea for Athenian sailors. It also applied to gay men.
