How to Say “I Promise” in Spanish

In Spanish, "I promise" is translated as lo prometo.
The phrase is used to give a sincere or formal assurance that you will definitely do something. It is derived from the verb prometer, which means "to promise".

What does it mean word for word?

The phrase lo prometo literally translates to "it/that I promise", where lo acts as the direct object meaning "it" or "that".

Which one should you use?

While lo prometo is a general way to say "I promise", you can use te lo prometo to make the phrase more personal by explicitly stating "I promise it to you".

How does it change in a sentence?

The word prometo is the first-person singular present indicative form of the verb prometer. In Spanish, the subject yo (I) is typically omitted because it is already implied by the verb ending.

How do you pronounce it?
