"Your children have grown up since I saw you last time."
Translation:הילדים שלךָ גדלו מאז שראיתי אותךָ פעם אחרונה.
I saw this in a "mark all correct translations" example. The other "correct translation" had הילדים שלכן, which seems to me to suggest that the speaker is addressing women (plural), but then concluded שראיתי אותך. which seems to indicate that the speaker is addressing only one person.
Can you explain?
You can't say פעם הקודמת when you mean "last time". הפעם הקודמת is noun + adjective, and in Hebrew, when they are definite, they both need a ה. Note that you can say: בפעם הבאה, the ה is contracted with the ב. I know this is confusing and I'm not sure I explained it very clearly, so ask away if you still have questions.
Fair enough, but DuoLingo (and I understand it's still Beta), said I needed to say פעם אחרונה (I forget where the ה's were, if at all...). So I was just wondering about אחרונה vs קודמת, not necessarily the specific placement of the ה. :-) Since this is how people speak, it seems to me that it should be allowed.
