[1] The glosses here are neuter plurals, nominative or accusative, which may indicate that the lexicographer has mistaken the headword for being the same, when in fact it is a nominative singular feminine noun. Possibly the reading of the headword should be a neuter plural noun or adjective like sfairi/a ('little balls') or sfairika/ ('ball-like'), or was perhaps misread for such. Compare Hesychius sigma2835, where forms of the same adjective are used to gloss the related adverb sfairhdo/n (which is glossed differently in the present entry below -- see n. 4).
[2] This verb (here in the present active infinitive) is unattested elsewhere prior to the Suda, but the same form does appear later in the poetry of Manuel Philes 2.1.898.
[3] Greek Anthology 6.282.5 (Theodorus), quoted also pi 1361, pi 1385, pi 1596.
[4] Possibly from commentary to Homer, Iliad 13.204, where the lemma occurs; cf. scholia ad loc. and Hesychius sigma2835.
[5] Basically the same statement is made about this gentleman in omicron 670 and chi 398, except in those entries he is called a sfairisth/s ('ball-player') rather than a susfairisth/s ('ball-mate'); cf. Athenaeus, Deipnosophists 1.18A [1.34 Kaibel]. To judge by the content of the other Suda entries, the statement may originate from commentary to the display of ball-gymnastics in Homer, Odyssey Books 6 and 8.
