Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
Ōrĭcos or Ōrĭcus, i, f., or Ōrĭcum, i, n., = Ὠρικός and Ὠρικόν, a seaport town of Illyria Grœca, now Ericho, Caes. B. C. 3, 8 sq.; Liv. 24, 40; Mel. 2, 3, 12; Prop. 1, 8, 20; Luc. 3, 187.
Hence,
Ōrĭcum, v. Oricos.
