[Middle English colyndore; probably from a Romance source akin to Old Provençal colador, strainer, from Vulgar Latin cōlātōr, from Latin cōlātus, past participle of cōlāre, to strain; see percolate.]
1368, probably alt. from M.L. colatorium "strainer" (with parasitic -n-) from L. colatus, pp. of colare "to strain," from colum "sieve." Fr. cognate is couloir, Sp. colador, It. colatojo.
