Oh, ça ? Non, c'était la ________ !
Oh, that? No, that was last time!
My Answer - dernière fois
Correct Answer - fois dernière
If "la dernière fois" and "la fois dernière" can be used interchangably (with "la dernière fois being more restrictive") why is my answer wrong ? I don't see any relative clause here as mentioned in the lesson.
Bonjour Shivam
"When last + [time phrase] means previous, dernier(s)/dernière(s) is placed after the noun."
The above is from the lesson.
If "la dernière fois" and "la fois dernière" can be used interchangably
This above is the comment in your query.
The point is that they cannot be used interchangeably -- before the noun, in an abstract sense, but after the noun, in a more concrete sense.
So your example, the meaning is to a time previously (Oh, that? No, that was last time), therefore
The answer is indeed "fois dernière", expressing a time previously. As per the lesson at the very top of this post
I hope this helps to explain.
Bonne continuation
Jim
