How do you say“我知道他，但我不认识他” in English?
汉语里知道和认识是两个不同的词，但英语里好像都是用“know”。那么下面这两句话怎么用英文表达呢？

1、我知道他（我们一个学校的），但我不认识他。
2、我认识他，但不怎么熟。

Answer

I think we use know for either, but use it as a comparison with something more definitive. Examples;

1. I know him (we are a school), but I don't really know him.
1. I recognise him, but I don't really know him.
1. I know him by sight, but I don't really know him.
1. I know of him, but I don't know him. <-- more distant

2. I know him, but I am not very familiar with him.
2. I know of him, but I am not very familiar with him.
