来口用英语怎么说

"来口" (lái kǒu) is a Chinese phrase that means "to come to one's mouth" or "to be on the tip of one's tongue." It is often used to describe the feeling of trying to remember something or recall a word or phrase that is almost, but not quite, at the forefront of one's mind.
This phrase does not have an exact equivalent in English. One way to describe this feeling in English might be to say that something is "on the tip of my tongue" or "just on the edge of my memory." Here are some examples of how this phrase could be used in English:
"I know I've heard that name before, but it's just on the tip of my tongue." (我知道我以前听过那个名字，但是它就在我的嘴唇上。)
"I can almost remember the answer to that question, but it's just not coming to me." (我几乎记得那个问题的答案，但是它就是想不起来。)
"I feel like I should know this, but it's just not coming to me." (我感觉我应该知道这个，但是它就是想不起来。)
This phrase is of Chinese origin and is not commonly used in English. However, the concept of trying to remember something or recall a word or phrase that is almost, but not quite, at the forefront of one's mind is universal and can be described in various ways in different languages.
