The headword appears to be an aorist active participle, masculine nominative plural, from *kuto/w, a denominative formation from ku/tos ('hollow'), kappa 2791. Yet neither it nor the compound derivative used in the quotation given (perikutw/santes, which also appears in kappa 2791 and tau 1164) occurs outside the Suda. In fact, no form of kuto/w or perikuto/w is otherwise attested.
