Editing Cockle (bivalve) (section)

==Alternative meanings==
The common [[English language|English]] phrase "[[wikt:warm the cockles of one's heart|it warms the cockles of my heart]]" is used to mean that a feeling of deep-seated contentment has been generated.

Differing derivations of this phrase have been proposed, either directly from the perceived heart-shape of a cockleshell, or indirectly (the [[scientific name]] for the type genus of the family is ''Cardium'', from the Latin for heart), or from the Latin diminutive of the word heart, corculum.<!-- ref Oxford English Dictionary --> Another proposed derivation is from the Latin for the ventricles of the heart, ''cochleae cordis'', where the second word is an inflected form of ''cor'', heart, while ''cochlea'' is the Latin for snail.{{Citation needed|date=February 2008}}
