Etymology
The word 'avulsion' originates from the Latin avulsio, which is derived from the verb avellere, meaning "to tear away." This verb itself is a compound of the prefix a- (away) and vellere (to pull, pluck, or tear). The core concept has always been one of forceful separation. In modern English, this literal sense of tearing away is preserved in medical contexts, referring to the traumatic separation of a body part. The term was also logically extended in legal and geological contexts to describe the sudden removal of land by natural forces, maintaining the essential idea of an abrupt, forcible detachment.
