Impersonal French

Impersonal expressions are those which do not have a specific subject, as in Il est difficile à dire.

Impersonal verbs have only one conjugation: the third person singular indefinite, or il, which in this case is equivalent to "it" in English.

In the passive reflexive construction, a normally non-reflexive verb is used reflexively in order to express the passive nature of the action, as in Ça se voit - That's obvious.
