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.

Hypaepa, ōrum, n., = Ὕπαιπα, a small town in Lydia, now Beréki, Ov. M. 6, 13; 11, 152; Petr. 133.
Hence, Hy-paepēni, ōrum, m., its inhabitants, Plin. 5, 29, 31, § 120; Tac. A. 4, 55.
