💡 Quick Rule
Sé has an accent when it means 'I know' or is a command to 'be'. 'Se' is for everything else.
The accent on 'sé' is like a brain thinking, 'I know!' or a crown for 'Be someone!'
- These aren't two versions of the same word. 'Sé' is a verb form, while 'se' is a pronoun. They just happen to sound identical.
📊 Comparison Table
| Context | se | sé | Why? |
|---|---|---|---|
| Knowing something | Él se sabe la respuesta. | Yo sé la respuesta. | 'Se' can be used reflexively with 'saber' (he knows it for himself). 'Sé' is the direct 'I know' form. |
| Giving a command | ¡Siéntese, por favor! | ¡Sé paciente! | 'Se' attaches to other command verbs to make them reflexive. 'Sé' IS the command 'be'. |
| General statements | Se dice que es el mejor. | No sé si es el mejor. | 'Se dice' is impersonal ('they say'). 'Sé' is personal ('I know'). |

When you mean 'I know', the verb is 'sé' and it always needs the accent mark to distinguish it from the pronoun 'se'.
Se feliz.
Sé feliz.
The command 'be' comes from the verb 'ser' and its form is 'sé' with an accent.
El niño sé levantó.
El niño se levantó.
The action of getting up ('levantarse') is reflexive, so it uses the pronoun 'se' without an accent.

Frequently Asked Questions
Do 'se' and 'sé' sound different when spoken?
No, they are pronounced exactly the same. The accent mark (la tilde) is purely for writing to help you tell the difference between these two completely separate words.
Why does 'sé' have two different meanings ('I know' and 'be')?
It's a coincidence of conjugation! 'Sé' is the 'yo' (I) form of 'saber' in the present tense. It's also the informal 'tú' (you) command form of 'ser'. You can always tell which one it is from the context of the sentence.
