Introduction

• Last grammar is commonly used to refer to previous actions at the time of the utterance, or what is the same, to express events that have already happened. The future is similarly grammatical used to refer to later actions at the time of enunciation, that is, actions that have not yet taken place. This grammar is used in contrast to refer to actions that are not past or future, that is, neither have happened yet not happen in the future, but occur at the time of enunciation, either exactly the same time or in a wider period of time that includes that particular time.
