Conjugation patterns
Verbs derived from dire and faire

Verb dire

The verb to say does vous dites in the second person plural of the present tense of the indicative. This is an exception to this form which usually ends in -ez.

But this is not valid for derived verbs from "dire" (except "redire" (to say again): contredire (to contradict), dédire (to deny), interdire (to forbid), médire (to slander), prédire (to predict). In this case, we say vous contredisez, vous médisez in a quite regular way.

Note that the exception is only for the indicative present. In the subjunctive, we say que vous disiez.

Redire (to say again) is conjugated like dire : vous redites. This is the only derived verb from dire like that.

It should also be noted that verb "maudire" (to curse) is a verb of the third group and is conjugated on the basis of ending and makes its past participle cursed.

In the simple past tense, saying has a circumflex accent vous dîtes whereas there is none in the indicative present.

Verb faire

The other exception of the second person plural of the present indicative is verb "faire" (to make, to do): vous faites. On the other hand, this time the derivatives of doing are conjugated on the same model as "faire": vous satisfaites. Finally, note that even if you write, nous faisons, it is pronounced like *nous fesons.
