Questions & Answers about C'est la deuxième fois cette semaine.
Why do we use fois here instead of temps for "time"?
In French, fois is used for occurrences or instances that you can count, like "the first time" or "three times". Temps refers to time as a general concept or duration (like "I don't have time"), and heure is used for clock time.
Could I say la seconde fois instead of la deuxième fois?
Why does the sentence use C'est instead of Il est for "It is"?
We use C'est to identify or introduce a noun phrase, especially when the noun has a determiner like la in front of it. Il est is generally used before an adjective on its own, for example Il est tard (It is late), or for clock time like Il est midi (It is noon).
Why is it cette semaine rather than ce semaine?
