CHAPTER 1 – Definition – Main clause – Proposition principale

A clause, known as une preposition in French, is a group of words that include at least a subject and a verb.

Sometimes, too, a clause can contain more than a subject and verb. In other words, a clause can contain one or more clauses within it. In this case, the clause being contained is called the proposition subordonnée (subordinate clause), while the containing clause is called proposition principale (main clause).

Another definition that can be useful: a main clause is a clause that can form a complete sentence standing alone, having a subject and a predicate. –> Je ne suis pas certain que vous soyez malade. I am not  certain that you are sick.
