"They can return to their places."
Translation:Ils peuvent retourner à leurs places.
Should "leurs places" actually be singular, in that each girl has her own place (just one place, not many). Does this sentence, the way it is written, imply that each girl has multiple places? I am remembering a high school French example like "Elles ont mis leur chapeau sur leur tête", singular chapeau and tête since each person has one hat and one head: if it were chapeaux and têtes, then the girls would have multiple heads to put their hats on! Someone, please illuminate this for me!
Yes, again, a plural subject can have a singular or a plural object.
- elles retournent à leurs places (same as in English)
- elles retournent à leur place (each one to her own place/seat)
Remember: "ils mangent une banane" does "mean one each" and "ils mangent des bananes" means either one each or several each.
"Revenir" = to come back here
"Retourner" = to go back to some other place.
This explains it well, I think: http://www.frenchasyoulikeit.com/retourner-revenir-rentrer-whats-the-difference/
In English "they" can represent 2 or more people, animals or things, irrespective of their respective genders.
In French, "elles" is used to translate "they" when there are 2 or more women or feminine animals or feminine things.
In all other cases, "ils" is used to translate "they" (2 or more people, animals or things, masculine or a mix of masculine and feminine ones)
