Morphology

invalidate = invalid (transparent) = in + valid + ate

This is a standard verb formation from the adjective 'invalid' meaning 'make invalid'.

Etymology

Invalidate comes from the prefix in- meaning 'not' and the root valid meaning 'strong' or 'officially acceptable', so to invalidate something is to make it 'not valid' and take away its legal or official force.
