Why aren't these two nouns separated by a dash? Can you write it with the dash or without it? Or are there specific rules?
You need to put a dash here. You need to put a dash between subject and predicate if both of them are nouns
Yes, I know, but I was asked to translate from Ukrainian to English, and the Ukrainian sentence did not have a dash through it, so that is why I asked about the dash.
I translated it as "My daughter is a student", and that was wrong answer. It said right answer is "My daughter is a female student". Really? :/ I know that студент means male student, and студентка - female, but in English both words would be translated the same. Am I wrong?
"My daughter is a student" is accepted too. You should report your variant using the "Report a problem" button, if you are sure that it is correct. Otherwise, there is no way to find out what was wrong. It could be a typo.
