The word "supplementation" derives from Latin supplementum (from supplere, "to fill up"), combining sub- (under) + plere (to fill). The root "supplement" entered English via Old French, retaining the core idea of "adding to complete." The suffix "-ation" (from Latin -atio) transforms the verb into a noun, denoting the process or result of supplementing. This reflects a logical progression: filling a gap (sub+plere) → the thing added (supplement) → the act of adding it (supplementation).
