"You are women."
My previous exercise started with גברים אתם and translated it as "You are men." So I followed that pattern and wrote נשים אתן. But this was marked wrong.
We have to understand that as in English We have (You) addressed to singular + an article (a - an) and (You) addressed to Plural (with no articles), there's a rule for the words You - Female plural form ( אתן ) and ( אתם ) You - male plural form. In the singular forms We have: ( אתה ) You male singular and ( את ) You female singular.
