✕Common Mistakes
Não tô muito afim.
‘tô’ is fine in casual speech but should be replaced by ‘estou’ in formal writing.
Não tô muito afim sair.
Do not add a noun after ‘afim’ without ‘de’; e.g., ‘Não tô muito afim de sair’ is correct, but ‘Não tô muito afim sair’ is wrong.
Não estou muito a fim.
When used as an adjective meaning ‘interested’, write it as one word ‘afim’, not ‘a fim’. The two‑word form belongs to the construction ‘a fim de’.

I’m not very inclined.
Não estou muito interessado.
I’m not very interested.
Não estou com vontade.
I don’t feel like it.
Cultural Tip
‘Tô’ is a hallmark of informal Brazilian speech; you’ll hear it in music, TV shows, and everyday conversation. In written Portuguese, especially in formal contexts, stick with ‘estou.’ Also, be careful not to confuse ‘afim’ (interested) with the prepositional phrase ‘a fim de’ (in order to), which has a completely different meaning.
