Questions & Answers about No gatees en el piso sucio.
Why does the verb end in -es if gatear is an -ar verb?
Because this is a negative tú command (telling someone not to do something). For regular -ar verbs like gatear, you form the negative command by taking the present tense yo form (gateo), dropping the -o, and adding the opposite ending for tú, which is -es. That gives us no gatees.
Is the verb gatear related to the word gato?
Why do we use en here? Doesn't that mean in?
The Spanish preposition en is very versatile. Depending on the context, it can translate to in, on, or at. Here, en el piso naturally translates to on the floor.
