Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
Ăres, is, m., = Ἄρης, the war-god Mars (in Plaut. jocosely made to correspond with bellator, warrior): si tu ad legionem bellator clues, at ego in culinā Ares, Plaut. Truc. 2, 7, 54. (For the A, which is always short in Lat., cf. Lucil. ap. Scaur. Orth. p. 2255 P., and Mart. 9, 12, with reference to Hom. Il. 5, 31.)
