why not Vaše děvčata ?
That's also possible. But what was your complete sentence?
I typed Vaší dívky, it is wrong but still the app accepts it, simply saying it is a typo. I think it should tell me it is wrong
That's how Duolingo works.
What does that mean? What is the difference between a typo and a wrong answer?
when do you use devcata and when do you e divky?
