Heart-shaped, with the point directed away from the base; used especially in botany to describe leaves.
From Latin cor meaning 'heart,' combined with the suffix -ate meaning 'having the form of.' Medieval botanists borrowed this Latin term to precisely describe leaf shapes.
Biologists use this term to describe leaves that look like playing-card hearts, and it's a perfect example of how scientists borrow everyday shapes to quickly communicate complex information across languages.
