Morphology

complementary = complement (semi-transparent) = complement + ary

Formed by adding '-ary' to 'complement' but the logical/technical sense ('mutually negating' or 'covering all possibilities') is a specialized extension and may not be obvious to an average learner.

Etymology

The word complementary comes from Latin parts com- 'with' and plete 'fill', the same root as complete. In logic it means two words are opposites that together 'fill' all the possible cases, so they cover every option.
