Questions & Answers about Sappiamo la verità su Marco.
Why do we use sappiamo here instead of a form of conoscere?
Where is the word for "we" (noi) in this sentence?
In Italian, you can almost always leave out the subject pronoun (like io, tu, or noi) because the verb itself changes to tell you who is doing the action. Sappiamo can only mean "we know," so adding noi at the beginning is optional and mostly just used if you want to add special emphasis.
I thought the preposition su meant "on". Why does it mean "about" here?
Is sappiamo an irregular form? It looks a lot like a regular verb ending.
