Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
anguĭfer (trisyl.), fĕra, fĕrum, adj. [anguis-fero], serpent-bearing: caput, Ov. M. 4, 741: Gorgo, Prop. 2, 2, 8.
Hence, subst.: Anguĭfer, fĕri, m. (as transl. of Ὀφιοῦχος), the serpent-bearer, the constellation Serpentarius or Ophiuchus, Col. 11, 2, 49; cf. anguitenens.
