UK: ɪnˈfɔːmətɪv | US: ɪnˈfɔːrmətɪv
adj. providing useful or interesting information
adj. intended to educate or enlighten
The word "informative" stems from the Latin informare ("to shape, educate"), combining in- (into) + forma (form). The root "inform" entered English via Old French, originally meaning "to train or instruct." The suffix "-ative" (from Latin -ativus) turns verbs into adjectives, giving "informative" its modern sense of "providing knowledge." The evolution reflects a shift from physical shaping (Latin) to intellectual enlightenment (English).
