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

Sapphō, ūs, f., = Σαπφώ, a celebrated poetess, born at Mytilene, in the island of Lesbos, who, on account of her hopeless love for Phaon, threw herself from the Leucadian rock into the sea. Under her name Ovid composed the fifteenth epistle of his Heroides, Sappho Phaoni; nom. Sapphō, Hor. Ep. 1, 19, 28; Stat. S. 5, 3, 155; Cic. Verr. 2, 4, 57, § 125; gen. Sapphūs, Ov. H. 15, 3; acc. Sapphō, Hor. C. 2, 13, 25; abl. Sappho, Plin. 22, 8, 9, § 20.
