compulsive

The word 'compulsive' originates from the medieval Latin term compulsivus, which itself is derived from the past participle stem compuls- of the Latin verb compellere, meaning "to drive together, force, compel." This verb is a compound of the intensive prefix com- and pellere (to drive, push), a verb with Proto-Indo-European roots. The core semantic logic evolved from the literal sense of being physically driven or forced, to the psychological concept of being driven by an internal, irresistible impulse. The suffix -ive then solidifies this meaning into an adjective describing the nature of such driven behavior.
