"We have ten nieces and nephews" should be accepted. Unlike some other languages, any group containing males does not default to male, so a group of 3 nieces and 7 nephews would be "10 nieces and nephews", not "10 nephews".
Okay, so it can be the following :
We have ten nephews.
We have ten nieces.
We have ten nieces and nephews.
We have ten nephews and nieces.
I'll report it if I see this sentence.
From which skill is it ? "Family" ?
Yes, that looks correct to me. I only ever hear it with "nieces" before "nephews" but I don't see why it can't also work the other way around.
Thanks, I reported it too. Yes, it is in "Family".
Why is "We have ten nieces" not accepted? There is no indication at all that the people referred to are male instead of female!
