What does obovate mean?
Obovate is an adjective describing a shape that is broader toward its tip and narrower toward its base. It is especially common in botany, where it is used to classify leaves according to their outline, and it is the inverse of ovate, which is broader toward the base. An obovate leaf may resemble an egg turned upside down, with its rounded end at the distal tip. The word can also be used more generally for objects or designs with this outline. In botanical identification keys, the distinction is important because leaf shape helps distinguish related species. Although obovate is most familiar to specialists, it is a precise and useful term for describing forms that are broader at the end opposite the point of attachment.

Where does obovate come from?
Obovate comes from Latin obovatus, a compound of ob- meaning “inverted” and ovatus, meaning “egg-shaped” or “ovate.” The prefix reverses the orientation implied by ovate, producing a term for an inversely egg-shaped form. The words ovate, ovule, ovoid, and ovum also reflect the Latin root ovum, meaning “egg.” English adopted the botanical form during the development of descriptive botanical terminology.
