Questions & Answers about Si tu oublies ton permis, tu risques d’avoir des problèmes au parking de l’aéroport.

Why is it Si tu oublies and not Si tu oublieras?

In French, after si meaning if, you normally use the present tense when talking about a real possible future situation:

• Si tu oublies ton permis... = If you forget your license...

Even though the meaning is future, French does not usually use the future tense after this si.

A very common pattern is:

• Si + present, present / future / imperative

For example:

• Si tu viens, je serai content. = If you come, I’ll be happy.
• Si tu oublies ton permis, tu risques d’avoir des problèmes.

So Si tu oublieras is not correct here.

Why is it oublies with -es at the end?

Because the verb is oublier and the subject is tu.

In the present tense, oublier is conjugated like this:

• je oublie / j’oublie
• tu oublies
• il/elle oublie
• nous oublions
• vous oubliez
• ils/elles oublient

So:

• tu oublies = you forget

The -es ending is the normal ending for most -er verbs with tu in the present tense.
