[1] LSJ s.v. I. (The present gloss is taken, verbatim, from the scholia to Aristophanes, Birds 816: see next note.) For LSJ s.v. II see kappa 1480.
[2] Aristophanes, Birds 816. (The accepted text has xameu/nh|, as in chi 75). "Should we call our city Sparta?" "By Heracles! Should I put spartê [a cord] on my city? Not even on my bedstead -- not while I still have a bedstead-band."
[3] Neuter keiri/on is so glossed in the Etymologicum Magnum and Etymologicum Gudianum, but is not otherwise attested in literature (Trapp s.v. adds Ludwich's orthographical lexica), and is probably a grammarian's fiction; the noun is derived directly from kei/rw "cut, crop" (kappa 1478).
