cf. the scholia to Homer, Iliad 13.443; and more on this headword (presumably related to ou)ra/ "tail") at omicron 950.
[1] This term, saurwth/r, is treated in the Suda at sigma 1261 (an entry shared with Photius, Lexicon sigma653 Theodoridis). Hesychius also discusses the word at sigma280 and sigma2092.
[2] Used of weapons, i)a/xw can mean "twang" (of a bowstring: see LSJ s.v. 2 at web address 1), but does not seem to have been used of the butt-end of spears. Translating as "twang" also makes it more difficult to render the etymological similarity of i)a/xw and i)axh/ (the latter does not seem to mean "twang" and is not normally used of weapons: see LSJ s.v. at web address 2).
[3] This is consistent with the gloss of i)/a that appears at iota 1, but note that the accent, according to LSJ (web address 3), should be i)a/ rather than i)/a if the word is to mean "voice" or "shout". There may be some confusion here and at iota 1. See also iota 219.
[4] cf. iota 71.
