Lewis & Short

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

Scaurĭānus, a, um, v. 2. Scaurus.

      1. 1. † scaurus, a, um, adj., = σκαῦρος [cf. σκαιός], with large and swollen ankles, having the ankles bunching out (cf.: varus, valgus), Plin. 11, 45, 105, § 254: illum Balbutit scaurum pravis fultum male talis, Hor. S. 1, 3, 48.

2. Scaurus, i, m. [1. scaurus], a frequent surname in the gens Aemilia and Aurelia. So, M. Aemilius Scaurus, whom Cicero defended in an oration, part of which is still extant.
Hence, Scaurĭānus, a, um, adj., relating to Scaurus: oratio, Mart. Cap. 5, § 441.
