The first gloss suggests that kabbali/s is derived from kataba/llw (cf. kappa 3); but then a different etymology is offered, from words for "manger" and "enough." The headword noun in this precise form is otherwise unattested (though see n. 2 below).
[1] Same gloss (for the aorist participle kabbalw/n) at kappa 3.
[2] Thus far the entry has a parallel in Etymologicum Magnum 482.18-20, though the headword there is ka/bbalis with the variant kaba/llhs and the glossing participle (for both) present-tense kataba/llwn. The noun kaba/llhs meant a nag or work-horse (cf. Hesychius kappa6), from Latin caballus; whence kaballi=na or kabali/na meant horse-dung (and Kaballinos was an alternative epithet for the emperor Constantine V Copronymus). The last sentence of the gloss suggests that the lexicographer has this sense in mind; cf. Eustathius, Commentary on the Odyssey 1.42.31 Stallbaum.
