From Akkadian karû (from Sum.) "grain pile" perhaps conflated with kurru "grain measure." LS2 separates ܟܘܪܝܐ and ܟܪܝܐ, taking the former from Greek κοριαῖος, but given the CPA spelling with w and that the Greek itself is almost certainly the same culture-word, that is a dubious distinction.
For the native lexicographic tradition as "grain storage" compare modern NENA bekāre < by n. + karyā, ‘lower part of house used for livestock and storage’, as pointed out by H. Mutzafi in "Akkadian substrate words and meanings surfacing
in Neo-Aramaic", Brill’s Journal of Afroasiatic Languages
and Linguistics 10 (2018):31.
