你好。I have a very simple question to ask, but I couldn’t find a clear answer anywhere.
I have seen both 我朋友 and 我的朋友 used. Is there any rule on when you should use 的 for possessive and when it’s not necessary? Is it always interchangeable? For example, is it ok to say 我哥哥, 我老师, 我中文不是很好 etc? Or do I need 的 here?
I am not a native speaker and may well be corrected. Usually we say 我的朋友 or 我的哥哥, 我的老师 however it seems that for 我 especially, but also for other pronouns, it is sometimes quite OK to drop the 的 when speaking.
