Etymology

The term "hard-core" originated in the early 20th century, combining "hard" (from Old English "heard," meaning solid or unyielding) and "core" (from Latin "cor," meaning heart or center). Initially used to describe the most dedicated or unyielding members of a group (e.g., "hard-core supporters"), it later expanded to describe extreme subcultures (e.g., "hard-core punk") and challenging situations. The logic reflects the idea of an unshakable, central intensity—whether in ideology, art, or difficulty.
