sim
/ˈsĩ/
The English word 'yes' is translated into Portuguese as sim.
The word sim is primarily used as a particle to indicate agreement or to answer yes to a question. It can also function as a noun meaning 'an affirmative' or 'a yes'. To express that something is certain, you can use Com certeza (certainly or for sure).
Meaning: word used to indicate agreement or acceptance (particle)
Which one should you use?
While sim is the standard way to say yes, its opposite is não (no). When you want to express excitement or great pleasure, you might use sim!, é! or assim! instead of a simple agreement.
Is there a formal and an informal way to say it?
In formal contexts, such as official procedures or radio communication, afirmativo is used instead of sim to mean 'affirmative'. You can also use the formal word decerto to mean 'indeed'. For informal situations, you might say Sim, claro to mean 'yes, of course'.
