"This is our daughter's boyfriend."

Translation: 这是我们的女儿的男朋友。

Having 的 twice is gramatically incorrect, should only be after 女儿

[TugRulz]

For my father and my mother, "Wo baba" and "Wo mama" can be used. Is not that the case for "Wo nu er" as well?

[WillowsofXihu]

Generally speaking in a row of 的 modifiers, all but the last 的 is omitted if possible.

Agreed thats what i did and it was an error

[AbunPang]

我女儿 is correct, it’s probably just not been added to the list of accepted sentences yet. Report it and I’m sure that will be corrected :)

[PatrickS888]

But it's not the nu er, it's her boyfriend!!!

[theFydra]

[這是我們女兒的男朋友] correct too

[PatrickS888]

[ALucyPhan]
