Morphology

motive = mot + ive

The adjective is recognizably related to the idea of motion and the suffix '-ive' forms an adjective, but the combining form 'mot' is not a standalone English word and the construction is Latinate rather than built from a common modern base, so the relation is only partially transparent to learners.

Etymology

Motive comes from the Latin root movere which means 'to move', the same root you see in motor and motion. So when we call a power 'motive' we mean it causes movement — it 'moves' machines or systems.
