Portuguese Phrase
Sim, eu sou.
Meaning
Literally translates to ‘Yes, I am.’ It is used to confirm an identity, a role, or a characteristic that has just been mentioned. The phrase carries a tone of certainty and can be slightly emphatic because the subject pronoun ‘eu’ is explicitly stated.
When to use
Use this response when someone asks you who you are, what you do, or whether a particular attribute applies to you—for example, ‘Você é estudante?’ ‘Sim, eu sou.’ It is also appropriate in role‑play or introductions where you want to stress your identity.

‘É’ is the third‑person singular of ‘ser’; the correct first‑person form is ‘sou’.

Cultural Tip
In Portuguese, the verb ‘ser’ is used for permanent or defining characteristics, while ‘estar’ describes temporary states. Saying ‘Sim, eu sou’ affirms a lasting identity (e.g., profession, nationality). In informal speech Brazilians often drop the pronoun and say simply ‘Sim, sou’, but keeping ‘eu’ adds emphasis and is common in formal or clarifying contexts.
