Explain why the following sentence is incorrect: es importante que dormes un poco antes de la excursion.

i know that dormes should be duermas, but if you could explain why it would be duermas, i would appreciate it! will give brainliest if it's original.

Es importante que duermas un poco antes de la excursión.

Explanation: Because the verb in this sentence must be conjugated in subjunctive mode: tú duermas.

The subjunctive mode which is a verbal mode that expresses an action, a process or a state as hypothetical, doubtful, possible or desired.

The meaning of this sentence is that it would be desirable to sleep a little before hiking.

Furthermore, the word "excursión" in Spanish is acute, because its stressed syllable is the last one, and as it ends in "n", it must have a written accent. Excursión.
