In Spanish, to conjugate the verbs, you must change the last letter of the verb in the infinitive and add the appropriate ending.
In past when we speak in plural to the verb in infinitive you must add the ending "n", in addition, to eliminate the ending "r":
Ustedes (beber) beben.
Ustedes (comer) comen.
Ustedes (relatar) relatan.
Ustedes (correr) corren.
Ustedes (bailar) bailan.
Ustedes (usar) usan.
In the past when we speak in the singular to the verb in infinitive only the termination "r" must be eliminated:
Usted (visitar) visita.
Usted (escuchar) escucha.
Usted (estudiar) estudia.
Usted (comer) come.
Usted (escribir) escribe.
Usted (ser) es.
Usted (beber) bebe.
Usted (vivir) vive.
Usted (respirar) respira.
