Morphology

valency = valence (transparent) = valence + y

Same morphological relationship as the chemical sense: derived from 'valence' with the -y/-cy nominalizing variant, and the biological meaning is a direct extension of 'capacity to combine/react'.

Etymology

Valency in biology also comes from the Latin valentia 'strength' and is related to value, and a helpful way to remember it is to think of 'how many things it can react with'. So for molecules or vaccines, valency tells the number of different items they can interact with or target.
