Learn Spanish (Latin America): El actor salió al escenario con su disfraz. - The actor went out to the stage in his costume.

Salió is the preterite (completed past) tense of the regular -ir verb salir (to go out / to leave). To form the "he/she/it" past tense for regular -ir verbs, you drop the -ir ending and add -ió. Since el actor is a "he," we use salió (he went out).

What does al mean before escenario?

Al is a mandatory contraction of the preposition a (to) and the masculine word for "the", which is el. Because escenario is a masculine noun, we must combine a + el into al (to the).

Does escenario mean "scenario"?

It can sometimes mean "scenario," but in the context of acting, music, or theaters, el escenario means "the stage." It is a very common false friend for English speakers!

The English translation says "in his costume." Why does the Spanish sentence use con (with)?

In Spanish, when describing someone wearing a specific item, accessory, or disguise, it is very common to use con (with). While the literal Spanish translation is "The actor went out to the stage with his costume," the most natural English phrasing is "in his costume."
