钥匙在哪儿用英语怎么说

"Where is the key?" in English would be "Where's the key?" or "Where are the keys?" depending on the context.

The origins of the word "key" come from the Old English word "cæg", which meant a "key" or "bolt". It then evolved into the Middle English "keye", and eventually into the Modern English "key".

Examples:

"Where's the key to the car?" (车的钥匙在哪里？)
"I can't find my keys anywhere." (我找不到我的钥匙了)
"Can you hand me the key to the cabinet?" (你能把柜子的钥匙给我吗？)
