Etymology
The word "useful" combines the root "use" (from Old French user, meaning "to employ") with the suffix "-ful" (from Old English -full, meaning "full of"). This structure literally means "full of use," reflecting its modern sense of being practical or beneficial. The suffix "-ful" is commonly added to nouns to form adjectives indicating abundance (e.g., "joyful," "careful").
