If a door, a wooden floor, an old bed, or the stairs creak, they make a long, high, complaining sound when someone opens them, walks on them, or sits on them. The noun is that sound itself.

a door, a wooden floor, an old bed, or the stairs門、木地板、舊床、或樓梯 creak會creak的話，when someone opens them, walks on them, or sits on them在有人打開、踩踏、或坐上去時，they make就會發出 a long, high, complaining sound一種長長、尖尖、像抱怨的聲音。The noun這個名詞 is指的就是 that sound itself那個聲音本身。

It often hints at age, or at someone trying to be quiet and failing. People also joke that their knees creak. Informal, and a little like the noise it names — not posh, not slang.

It often hints at它常常暗示著 age年紀老舊，or at或是 someone trying to be quiet and failing有人想安靜卻沒能安靜。People也有人 joke開玩笑說 their knees自己的膝蓋 creak會creak。Informal是非正式用語，and a little like the noise it names也有點像它所指的那個聲音——not posh不是高雅用語，not slang也不是俚語。

The word is old: Middle English creken, from Old English cearcian (“to chatter, creak, gnash”), with the sounds swapped around, from an old crash/crack verb that is, in the end, imitative. It sits in the same old family as crack.
