Questions & Answers about Eles não precisam dos bilhetes.
Why is there a dos in this sentence instead of just de?
Why doesn't the Portuguese sentence have a word for "do" like in "do not need"?
Is it mandatory to include Eles at the beginning?
It is not strictly mandatory, but it is often helpful here. In Portuguese, you can usually drop the pronoun (like "I" or "we") because the verb ending tells you who is doing the action. However, precisam is shared by eles (they, masculine), elas (they, feminine), and vocês (you plural). Including Eles prevents confusion if the context isn't already clear.
How can I tell from this sentence that bilhetes is a masculine word?
