你在乱讲用英语怎么说

在英语中，当一个人乱讲，我们通常会用 "ramble" 或 "rambling" 来形容他的言辞。这个词源自中世纪英语中的 "rammelen"，意思是 "漫步" 或 "闲逛"。
例句：
He kept rambling on and on about his vacation, and I couldn't get a word in edgewise. 他不停地漫谈他的假期，我根本没有机会插话。
She has a tendency to ramble when she talks, so it can be hard to follow what she's saying. 她说话时有时会喜欢漫谈，所以很难听懂她在说什么。
