Morphology

principal = princip + al

The adjective-forming suffix '-al' attaches to the combining form 'princip-' (not a standalone modern English word), so learners cannot reliably derive the financial sense from familiar English components.

Etymology

Principal for money comes from the Latin root princip- meaning 'first' or 'beginning', so it is the original 'first' amount you borrow or invest on which interest is calculated.
