Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
cămīno, no perf., ātum, 1, v. a. [caminus], to make like an oven or furnace (very rare; perh. only in the foll. pass.), Plin. 16, 6, 8, § 23: caminata fossura, id. 17, 11, 16, § 80.
