the quality of being useful
How useful or helpful something is for a goal or task.
用法パターン：
the usefulness of [something] for [a purpose]
よくある間違い：
Learners sometimes confuse "usefulness" with "use" and say *"the use of this tool is that it is easy"* when they really mean its practical value; in that case, "the usefulness of this tool" fits better. Another common error is treating "usefulness" as countable (e.g., *"many usefulnesses"*); it is almost always used as an uncountable noun ("the usefulness of", "its usefulness").
