Morphology

quadrivalent = valent (transparent) = quadri + valent

The meaning 'having four [targets/parts]' follows directly from 'quadri-' (four) + 'valent' (having valence/power), a standard compositional pattern in medical/scientific contexts.

Etymology

Quadrivalent is built from quadri- 'four' and valent 'having power', so it describes something that has four parts or can act against four different targets.
