Why is "The kid" not a valid option? the correction says that "the boy" is the only option even though "the child" is given as one of the translations when you hover over it.
I believe girl is הילדה (well, technically that's the girl...without the "the" it's ילדה --note the ה on the end). It's pronounced yel-dah, as opposed to boy, which is pronounced yeled (and has no ה on the end).
So: the boy: הילד
the girl: הילדה
I hope that helps clear it up!
My mnemonic for keeping them straight: When you ask the boy his name, he will yell Ed! When you ask the girl what she wants, she will yell dah! ("doll")
i'm Hebrew native speaker. The boy is הילד and the girl is הילדה. In Hebrew the words are connected. Anything you say in Hebrew will be connected to an example - in the Apartment it's בדירה The letter B ב its' in in hebrew and it connected to the word in the apartment. I hope it will help you...
