Underused means something is not used as much as it could be or should be — the capacity is there and it is going to waste. The complaint inside the word is aimed at the situation, not at the thing itself: an underused library is a perfectly good library that too few people visit; underused land is land sitting empty; an underused railway line carries few passengers.

UnderusedUnderused means指的是 something is not used as much as it could be or should be一個東西沒有被用到它原本可以或應該達到的程度 — the capacity is there能力／空間明明就在那裡 and it is going to waste卻白白浪費掉。The complaint inside the word這個字裡帶的抱怨 is aimed at the situation針對的是狀況, not at the thing itself而不是那個東西本身: an underused library一間underused（使用率偏低）的圖書館 is a perfectly good library that too few people visit本身是間很不錯、只是去的人太少的圖書館; underused landunderused（閒置）的土地 is land sitting empty就是空在那裡的土地; an underused railway line一條underused（使用率偏低）的鐵路線 carries few passengers載的乘客很少。

It is very often used about people and their abilities, and there it stings gently: an underused employee has skills the job never asks for, and 'her talents are badly underused in that role' is a sympathetic thing to say about someone. Sports commentators use it constantly about players kept on the bench.

It is very often used about people and their abilities這個字很常用來講人和他們的能力, and而在那種情況下 there it stings gently它帶著一點溫和的刺: an underused employee一個underused（能力沒被善用）的員工 has skills the job never asks for有工作用不到的技能, and而 'her talents are badly underused in that role'「her talents are badly underused in that role」（她的才能在那個職位上完全被浪費了） is a sympathetic thing to say about someone是一句帶著同情的評論。Sports commentators運動球評 use it constantly經常用這個字 about players kept on the bench來講被放在板凳上的球員。

It is a mild, reasonable-sounding, slightly official word — councils, managers, and reports love it, because it points at waste without accusing anyone directly. You will also meet 'underutilised', which means exactly the same thing but sounds heavier and more corporate; 'underused' is the plainer, better choice. It usually appears with an adverb of degree: 'badly', 'seriously', 'chronically', 'sadly' underused.
