Able to help achieve a goal or make a task easier. It describes something that has practical value or benefit.
From 'use' + '-ful' (full of), first recorded in the 1500s. 'Use' itself comes from Latin 'ūtī' (to use).
Useful literally means 'full of use'—packed with possible purposes. Something can be small and cheap but very useful, which is why usefulness and price don’t always match.
