What does compulsive mean?
Compulsive describes behavior driven by an irresistible inner urge rather than by free choice — actions performed repeatedly, often irrationally, and difficult to stop despite unwanted consequences. It appears most frequently in psychological contexts: a compulsive gambler, a compulsive shopper, or compulsive hand-washing are all examples of conduct governed by powerful internal drives. The word derives from the Latin verb 'pellere' (to drive), via 'com-pellere' (to drive together or force), so its core meaning of being pushed toward action has remained remarkably stable for centuries. In clinical usage it pairs closely with 'obsessive', as in obsessive-compulsive disorder, where obsessive refers to intrusive thoughts and compulsive to the repetitive behaviors they provoke. Compulsive differs subtly from impulsive: an impulsive act is sudden and unpremeditated, whereas a compulsive act stems from a persistent, recurring pressure. The adjective also exists as a rare noun meaning a person subject to such urges.
Resulting from, or relating to, an irresistible inner urge that is difficult or impossible to control; done repeatedly and often without rational justification.
"Her compulsive checking of the locks kept her awake at night."
Frequently used attributively before nouns (compulsive liar, compulsive spender).
A person who behaves compulsively; someone subject to compulsions.
"As a compulsive, he found it nearly impossible to leave the casino."
Chiefly used in clinical or psychological writing.
The Latin root of 'compulsive' means 'to drive' — literally, something that pushes you forward whether you want to go or not.

Etymology of compulsive
Compulsive comes from the Latin verb 'pellere', meaning 'to drive or push', combined with the prefix 'com-' (together, thoroughly), forming 'compellere' — to drive forcibly. English acquired the related noun 'compulsion' in the early 15th century, with the adjective 'compulsive' following later, around the early 17th century. Its modern psychological sense — describing irresistible repetitive behavior — developed in the 19th and 20th centuries alongside the growth of clinical psychology. The same Latin root gives English many other words, including impulse, expulsion, propulsion, repel, and pulse.
