Note: For English loanwords going back to dískos see dais, desk, dish entry 1, and disk entry 1. Greek dískos is generally said to be a derivative of the verb dikeîn "to throw, cast, fling" (aorist only), presumably as a simplification of *dikskos, with a suffix -sk-. P. Chantraine is certain of this in Dictionnaire étymologique de la langue grecque, but less confident in La formation des noms en grec ancien, where this etymology is followed by a question mark (p. 405). Clearly, if such a suffix existed in Greek, the evidence is meager (and the productivity of the diminutive suffix -isko- is not relevant). R. Beekes (Etymological Dictionary of Greek) suggests that the earlier form was *diks-, which together with dikeîn is of non-Indo-European substratal origin, citing Edzard Furnée, Die wichtigsten konsonantischen Erscheinungen des Vorgriechischen (Mouton, 1972), p. 297.
