isn't: "the girl" also correct ?
I put, " the girl wants to study" but it counted it wrong. Shouldn't it still be correct?
No, because Bé means little
"Little girl wants to study" is wrong? Is "the" important in Vietnamese?
"The" is important in English. You need an article (or a determiner) in order for a sentence to be grammatically correct, unless the sentence is generic, in which case the subject should be plural.
The girl wants to learn should be correct
If boy is acceptable for đua trê then girl should definitely be acceptable for "bé gái"!!!
