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.

Ĭŏcasta (quadrisyl.), ae, and Ĭŏcastē, ēs, f., = Ἰοκάστη, the wife of Lāïus, and mother of Œdipus, whom she married unknowingly, and had by him Eteocles and Polynices.
Form Iocasta, Stat. Th. 1, 681; Hyg. Fab. 66.
Form Iocaste, Hyg. Fab. 67; 242.
