quantivalence

English

Etymology

From Latin quantus (“how much”) + English -i- (interfix inserted between morphemes of Latin origin for ease of pronunciation) + Latin valentia (“bodily strength; health; vigour”) (ultimately from Proto-Indo-European *h₂welh₁- (“to rule; powerful, strong”)) + -ence (suffix meaning ‘having the condition or state of’), coined by F. O. Ward who communicated it to the German chemist August Wilhelm von Hofmann (1818–1892), leading him to coin the German word Quantivalenz from which valence is derived.
