Morphology

propellent = propel (transparent) = propel + ent

The noun is built directly from 'propel' with a regular deverbal suffix, so the meaning of something that propels is easy to infer.

Etymology

Propellent comes from pro- 'forward' and pellere 'to drive', the same root as propeller, a device that pushes a boat or plane. So a propellent is a substance that 'drives' or gives the push that moves rockets and engines.
