Etymology and Origin of cardi
The core origin of cardi is ancient Greek kardia, meaning heart. Over centuries, that root passed into Latin and then into modern medical terminology, usually as cardio- or cardi- in English words like cardiology and myocardium.
As a nickname, Cardi B traces back to her stage name, which in turn is a shorthand derived from the rum brand Bacardi. For fashion slang, the clipped form cardi for cardigan likely emerged from casual speech patterns that shorten longer clothing names, similar to tee for t-shirt.
