"लड़कियों के बच्चे"
अनुवाद:The girls' children
The girls kids-> is it wrong or not??if correct why is it correct answer?
And what is the difference between child and kid?
It should be accepted but it is informal, formal says young goat.
Also if you read anywhere in books or listening lectures. You will find child not a kid.
The apostrophe ( ' ) is used after the 's' in 'girls' in this case to show that 'girls' is in the plural form. If you write 'The girl's children' that would mean that there is only one girl, and the children are only of one girl. But 'The girls' children' shows that it is plural and that there are many girls.
