use suitable preposition in the following sentence:Nous voulons aller ...............Mexique.

The appropriate preposition to use in the sentence "Nous voulons aller ............... Mexique" is "au." Thus, the completed sentence is: "Nous voulons aller au Mexique."

Explanation

In French, the preposition "à" means "to," and when combined with the definite article "le," which means "the," it contracts to form "au." The context here indicates that you want to express going to a country, "le Mexique" (the Mexico), which requires the use of "au" as a contraction. This is a common structure in French when discussing locations, particularly countries and geographical regions.

So, the preposition "au" aids in conveying the intended meaning clearly and correctly.
