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

†† pădi, ōrum, m. [Gallic], pitch-pines, Plin. 3, 16, 20, § 117.

Pădus, i, m., the Po, the principal river of Italy, Liv. 5, 33, 10; Mel. 2, 4, 4 sq.; Plin. 3, 16, 20, § 117: sive Padi ripis, Verg. A. 9, 680: populiferque Padus, Ov. Am. 2, 17, 32.

  2. B. Pădā-nus, a, um, adj., of or belonging to the Po: silvae, Sol. 20: culices, Sid. Ep. 1, 8.
