Questions & Answers about C'est une grande récompense.
Why do we use C'est here instead of Elle est, since récompense is feminine?
When you are identifying a noun that is introduced by an article (like une, un, la, or le), you must use c'est. You generally use il est or elle est when describing something using only an adjective (like Elle est grande). Since we have the full noun phrase une grande récompense, c'est is the correct choice!
Why does grande come before the noun? Don't French adjectives usually go after?
