Morphology

principal = princip + al

The adjective is formed with '-al' on a non-standalone combining form 'princip-', so the meaning 'most important' is not transparently derivable by learners from visible English components.

Etymology

Principal as an adjective comes from princip- meaning 'first' or 'chief', the same idea you see in the word prince, so it means the 'most important' or main thing.
