Learn Spanish (Latin America): Traigo la comida a la fiesta.

The verb traer (to bring) has an irregular yo (I) form in the present tense. Instead of following the normal rules, it changes to traigo. The other forms are regular (like traes and traemos), so you only have to memorize this special "I" form!

Do I need to say yo traigo to mean "I bring"?

You don't have to! In Spanish, you can usually drop subject words like yo (I) because the verb itself already tells us who is doing the action. Since traigo specifically means "I bring", adding yo is only needed if you want to emphasize that you are the one bringing the food.

Could I use llevo instead of traigo to say I am taking food to the party?

It depends on where you are! Traer means "to bring" (moving something towards the speaker or the listener). You use traigo if you are already at the party, or if you are talking to someone who is at the party. If you are at home talking to someone who is also not at the party yet, you would use llevo (I take) because you are moving the food away from your current location.

Why do we use a for "to" in a la fiesta?
