Morphology

co-principal = principal (transparent) = co + principal

The meaning is directly built from the productive prefix 'co-' meaning 'together/jointly' plus 'principal'; the sense 'sharing main responsibility' follows standard English word-formation.

Etymology

Co-principal combines co- 'together', as in cooperate, and principal 'main' or 'head', as in a school principal. So, as an adjective, co-principal describes something that shares the main responsibility with others.
