Ok, i typed in the first 5 characters. Why do i have to put in the last two?
the last two characters mean "friend." without the characters your sentence means "that is our"
Yes. And it also means a complete sentence That is ours. We don't normally say that for a person (neither do we in English). : )
Do I need 的 in this sentence? Or is it ok to omit it
Can you also say：这是我们的朋友。
？Or has it to be 那？
Hello past Adrian!
Yes it has to be 那, otherwise it would mean "this" instead of "that".
Your future Adrian
Thank you so much!
Your future self will be grateful, some time in the past.
