Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
The word Dionaeus could not be parsed. Trying a normal dictionary lookup:
Dĭōnē, ēs (-a, ae, Cic. N. D. 3, 23, 59), f., = Διώνη.
- I. The mother of Venus, Cic. l. l.; Hyg. praef.; Claud. Rapt. Pros. 3, 433.
Hence, Dĭōnæus, a, um, adj., of Dione: vestis, the garment worked by Dione for her daughter, Claud. Epith. Pall. et Cel. 102.
Far more freq. as in Greek,
- II. Venus, Ov. F. 2, 461; 5, 309; id. Am. 1, 14, 33 al.
Hence, Dĭōnæus, a, um, adj., of Dione (Venus): mater, Venus herself (with reference to Aeneas), Verg. A. 3, 19; hence, Dionaeus Caesar, as the descendant of Iulus, Aeneas, and consequently of Venus, id. E. 9, 47: columba, sacred to Venus, Stat. Silv. 3, 5, 80: flores, Col. 10, 286: antrum, Dione’s grotto, as the scene of love and love-songs, Hor. C. 2, 1, 39.
