Sense: verb/1
All four words describe applying force to cause forward movement, but they differ in intensity and context. 'Push' is the most general — you can push a door open, a cart, or a person gently. 'Drive' suggests continuous, powered motion; you drive a car or a machine pushes a conveyor belt steadily. 'Thrust' implies a sudden, sharp, or forceful push, often in a specific direction — think of thrusting a sword forward or the thrust of a rocket engine. 'Propel' sits between 'push' and 'thrust' in force: it is stronger and more deliberate than 'push' but less sudden than 'thrust', and it almost always involves a direction or destination. For example, a fan propels air across a room (steady, directed force), whereas a sudden wind thrusts a door open (quick, sharp force).

Etymology
The word 'propel' comes from the Latin verb 'propellere', which was formed by joining 'pro-' (meaning forward) with 'pellere' (meaning to push or drive). It entered English in the 1400s through Middle French. Related words include 'propeller' (the bladed device that pushes a boat or plane forward) and 'propulsion' (the force that drives movement).
