Il y sera - French Mistake

Mistakes will always be made in French, and now you can learn from them.

Wrong: Il y sera

Right: Il y aura

Explanation: The French expression il y a means "there is." The actual verb in the French expression is avoir (literally "to have"), not être ("to be"). So when you want to use this expression in another tense or mood, you have to remember to conjugate avoir for that verb form.

   il y a - there is (present)
   il y avait - there was (imperfect)
   il y a eu - there was (passé composé)
   il y aura - there will be (future)
   il y aurait - there would be (conditional)

Note: While il y sera does not mean "there will be," it does have a meaning in French - "he will be there":

   Pierre est en France. Il y sera pendant trois mois.
   Pierre is in France. He'll be there for three months.
