Learn French: Vous devriez éviter ce geste dans ce pays. - You should avoid this gesture in this country.

The verb devoir usually means "must" or "to have to", so the present tense vous devez means "you must". However, this sentence uses the conditional tense (vous devriez) to soften the meaning to "you should". It turns a strict obligation into helpful advice.

Why is éviter in its infinitive (unconjugated) form?

In French, when two verbs are paired together to express a single idea, only the first verb is conjugated. Because devriez is already conjugated to match vous, the second verb (éviter) stays in its dictionary form.

The word pays ends in an "s", so why do we use the singular ce instead of the plural ces?

The word pays (country) is a bit tricky because it naturally ends in an "s" even in its singular form! Since we are talking about just one country here, we use the singular masculine word for "this" (ce). If we wanted to say "these countries" in the plural, it would be ces pays.

Why do we say dans ce pays instead of en ce pays?
