I think when you are referring to family members you don't use the article. But I could be wrong!
You are right!
I see - thank you both for this
Sounds like one of the rubbish pick-up lines from flirting....
Is "How's your mother" wrong in any way?
How's your mother, while informal, is correct.
DL usually accepts contractions, even though their own sentences are often hopelessly stiff.
In other examples, duolingo insists on articles for family members. Weird...
You may know by now, but singular family members don't need articles while plural ones do.
I miei fratelli.
This is still useful, thank you
Can the duolingo people speak English? I had “How is your mother going? Marked wrong. It suggested “how is your mother doing” as correct.
For prior question. How interesting that fratelli = brothers & siblings. Grazie mille
