Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

cŏquīnātōrĭus (cŏcī-), a, um, adj. [coquina], of or pertaining to the kitchen (late Lat.): instrumentum, Dig. 34, 2, 19, § 12: vasa, ib. 33, 9, 6.
Hence, subst.: COCINATORIVM, a kitchen, Inscr. Orell. 1359.
