What does avulse mean?
To avulse is to tear something away forcibly, most commonly used in medicine to describe the violent detachment of skin, a limb, a tooth, or other tissue from the body. The word derives from the Latin avellere, meaning 'to pluck or pull away,' which also produced the related noun form avulsion — the standard term clinicians use when naming such an injury. Because avulse implies ripping rather than precise incision, it conveys a sense of trauma: an avulsed finger differs fundamentally from an amputated one, having been wrenched free rather than cleanly severed. Outside medicine, the verb appears occasionally in legal contexts, where avulsion can describe the sudden removal of land by floods or other forces of nature. Readers are likeliest to meet avulse in surgical reports, dental discussions of knocked-out teeth, and accounts of serious accidents.

The Latin verb behind 'avulse' — avellere, literally 'to pluck away' — also gave us the word for seizures, making 'avulse' and 'convulse' unlikely siblings from one ancient root.

Etymology of avulse
Avulse comes from the Latin verb avellere ('to tear or pluck away'), formed from ab- ('away') plus vellere ('to pull or pluck'). This same root gave English several sibling words sharing the '-vulse' pattern, including convulse, evulse, and revulse, all entering English through post-classical Latin and appearing in English texts from around the early seventeenth century onward. Its derivative avulsion remains far more common than the verb itself in modern usage.
