Learn Spanish (Spain): Salgo a la calle. - I am going out to the street.

The verb salir (to go out) has an irregular "I" form. Instead of following the normal rules, the yo form adds a "g", making it salgo. The rest of the verb follows the regular rules (like tú sales or él sale).

Why doesn't the sentence start with yo (I)?

In Spanish, the verb ending tells you who is doing the action. Because salgo can only mean "I go out", the word yo is optional. Spanish speakers usually leave it out unless they want to add special emphasis.

The translation says "I am going out", but isn't salgo just the simple present tense?

Yes! In Spanish, the simple present tense is very flexible. Salgo can mean a general habit ("I go out") or an action happening right at this exact moment ("I am going out").

Why do we use a before la calle?

The word a generally means "to". When you use a verb of motion like salir to show where you are heading, you connect it to your destination with a. Here, it means you are going out "to" the street.
