Aristophanes, Acharnians 83 (here missing the word xro/nou: see web address 1), partly drawing on the scholia thereto (but see n.2 below); cf. pi 214.
[1] The headword (extracted from the quotation) is aorist indicative active, third person singular, of cuna/gw.
[2] A favourite Aristophanic sexual target (see kappa 1736; OCD4 Cleonymus) -- but mistakenly adduced by the lexicographer here. Instead, as is quite clear from the passage itself, the subject is the constipated Great King of Persia, and the length of time -- eight months -- it took his anal sphincter to return to normal.
