Etymology: "Informativeness" is a straightforward formation: the adjective "informative" with the noun-forming suffix "-ness" attached. The adjective itself is built from "inform," which came into English from Old French "enformer" and ultimately from Latin "informare," meaning to shape, form, or give form to something. The original sense was thus about giving shape to a mind or character, and only later did "inform" come to mean telling someone something. The adjective "informative" was formed in English by adding the suffix "-ative," which comes from Latin "-ātivus" through Old French "-if," to "inform." The suffix "-ness," which descends from Old English "-nes," turns that adjective into a noun naming the quality of being informative, and the result is a word for how much useful information something contains. Because "-ness" is productive, it can be attached to nearly any adjective, which is why the noun is easy to form even though it is long.
