What does it mean word for word?
The phrase consists of two parts: lo, which is a direct object pronoun meaning "it" or "that" and sé, which is the first-person singular present indicative of the verb saber (to know). Literally, it translates to "it/that I know."
Which one should you use?
Use lo sé when you are referring to a fact or a piece of information. Do not use it if you mean you are acquainted with a person or a place. In those instances, you should use lo conozco.
Is it said differently in some regions?
In Spain, the word Vale can be used to mean "I know" in certain contexts, similar to how one might say "Okay."
How does it change in a sentence?
In Spanish, you cannot simply say sé to mean "I know that". You must include the object pronoun lo to represent the thing that is being known.
How do you pronounce it?
/lo se/
Did you know?
- Spanish is a 'pro-drop' language where the subject 'I' is omitted, but the object 'it' in lo sé must remain for the sentence to be correct.
- Using lo sé with a dismissive tone or a specific gesture can be perceived as rude, implying the other person is stating the obvious.
- The spelling of sé includes an accent mark to distinguish it from the word se, which is a reflexive pronoun used in many different verbal constructions.
