Questions & Answers about Meninos, não pisem a relva, é proibido.
Why does the verb pisar become pisem in this sentence?
Why is there no Portuguese word for 'on' in pisem a relva?
In English, we say 'step on the grass', but the Portuguese verb pisar does not use a preposition. You simply act directly on the object. So, it translates literally as 'don't step the grass'.
Since a relva (the grass) is feminine, shouldn't it be é proibida?
