Here's a breakdown:
* o: The definite article "the" (masculine singular)
* homem: The word for "man"
However, there are other ways to say "the man" depending on context and formality:
* o senhor: A more formal way to address a man, often used for older men or strangers.
* o rapaz: A young man.
* o indivíduo: A more formal and neutral way to refer to a man, similar to "the individual."
It's important to choose the right word depending on the situation.
