俚語學習之as clear as mud

as clear as mud這個習慣中的“clear”是“清楚”，“mud”是“泥巴”，這兩個單詞根本就是風馬牛不相及，因為“泥巴”從來都是“渾濁骯臟”的，不可能是“干凈”的。

那會不會是這個習語有問題？

as clear as mud

答案肯定是否定的，如果有問題的話老王就不會放在這讓大家看了。

其實這個習語類似中文的反話，“像泥巴一樣干凈”，說白了就是“非常臟”、“非常渾濁”，因為沒有泥巴是干凈的，這個習語可以引申為“莫名其妙”、“難以理解”。例如：This doesn't make sense. It's as clear as mud.這說不通。簡直是莫名其妙。
