Help - au secours s'il vous plait !
Instead of writing 'deuxieme etage', I wrote 'premier etage'. I have always understood that the first floor, (which we Americans also call the ground floor), is the 'rez-de-chaussee', and what we in the U.S. call the second floor is 'le premier etage'. Collins dictionary defines 'second floor' as ' (US) le premier etage', which is what I wrote, and it was marked wrong.
I would appreciate an explanation as to the correct usage of 'rez-de-chaussee' vs. 'premier etage' vs.' deuxieme etage.
Perhaps a hint as to the US vs British usage would be helpful in this exercise.
Also, when is it appropriate to use 'les escaliers' vs. 'l'escalier'? Collins lists them both as correct.
Merci beaucoup et bonne continuation !
