Morphology

excite = cite (opaque) = ex + cite

The technical sense 'to raise to a higher energy level' is not inferable from 'cite' and thus is opaque despite historical composition.

Etymology

Excite comes from the Latin parts ex- 'out' and citare 'to move', which gave the idea 'set in motion'. So in physics to excite an atom or an electromagnet is to make it move to a higher energy state or start working, following the same idea of 'making move'.
