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

Massȳli, ōrum, m., = Μασσύλιοι, a people in Africa, to the east of the Massaesyli, Plin. 5, 4, 4, § 30; Verg. A. 6, 60; Sil. 4, 512; 16, 171; Prud. στεφ. 4, 46; called Maesuli, Liv. 24, 48, 13.
