Also, there are a lot of times in spanish where a verb conjugation ends up as an exact spelling of a noun or adjective. You have to use the rest of the sentence to know which is intended. consider the following sentence....
"Ella cocina en la cocina."
The first one is the conjugated verb (Cocinar - To Cook) so its She cooks (ella cocina), the second one is the noun Kitchen (cocina). Be on the lookout for these.
