## Meaning

Especially of food or drink (particularly an alcoholic beverage): to cause someone to feel deeply warm and comfortable; to comfort, to satisfy.

## Examples

- The sight of the family gathered around the fireplace, sharing stories and laughter, truly warmed the cockles of his heart on that bitter winter evening.

## Origin

The expression is first attested in 1671. Its origins are generally attributed to one of two anatomical observations, neither of which is particularly romantic. The first suggests a corruption of the Latin *cochleae cordis*, referring to the ventricles of the heart. The second proposes a visual comparison between a human heart and the shape of a closed cockle, a European bivalve mollusk of the family Cardiidae. The underlying root is the Proto-Indo-European *ḱḗr, which serves as the ancestor for various terms related to the heart. Whether one is referring to a Latin ventricle or a common mollusk, the mechanism of warming remains the same.
