Cordiform is an adjective that means heart-shaped.

The ancient Greek word Kardia (CAR dee uh) meant ‘heart.’ After traveling through Latin and Middle English, it landed in modern English to be used in words like cardiologist, which refers to the medical specialty of hearts. The word was then combined with the suffix F-O-R-M, which means ‘shape or form’. Here’s an example of our word of the day in use:

That cordiform branch on the tree seemed awfully romantic when we spotted it on Valentine’s day. It was lovely to see something heart-shaped on a day dedicated to love.
