Word History

Etymology

borrowed from Greek óstrakon "earthen pot, potsherd, hard shell of a mollusk or tortoise," of uncertain origin

Note: Greek óstrakon, as well as óstreion, óstreon "bivalve mollusk, oyster" (see oyster), have traditionally been taken as derivatives from Indo-European *h3esth1-r-, supposedly a heteroclitic stem with an -n- counterpart in Sanskrit ásthi, genitive asthnáḥ "bone," from a base *h3esth1- (or *h2osth1-), reflected more directly in Greek ostéon "bone" (see osteo-, osseous). The word óstrakon could be a derivative with a suffix *-n̥-k-, seen also without -r- in ostakón "lobster, crayfish" (see astaxanthin). These suppositions have been challenged by R. Beekes (Etymological Dictionary of Greek, Brill, 2010), who rejects the existence of both the heteroclitic base and a supposed suffix *-n̥-k-, and takes the entire set of words as of substratal origin, with -ak- and -ei- (from *-ay-) as pre-Greek suffixes.
