usefulness
UK: ˈjuːsf(ə)lnəs | US: ˈjuːsf(ə)lnəs
n. the quality or state of being useful; practical value or effectiveness.
The word "usefulness" is derived from the Middle English term "useful," which combines "use" (from Old French "user," meaning "to employ") and the suffix "-ful" (Old English "-full," meaning "full of"). The suffix "-ness" (Old English "-nes") converts the adjective "useful" into a noun, denoting the state or quality of being useful. This construction follows a common pattern in English where "-ful" adjectives are nominalized with "-ness" to abstract their qualities (e.g., "kindness" from "kindful").
