The forms we can give to the verb depending on how we want to present what the verb expresses are called moods. These moods are three: the indicative, the subjunctive, and the imperative. The indicative reveals something certain and real. It takes the negation δε(ν). On Saturday, I will go on a trip. In the end, we will not go to the theater. The subjunctive reveals something we want or expect to happen. It takes the negation μη(ν). Let's rest a little. It is time to rest. Let's not have negative thoughts. The imperative reveals a command, desire, or wish. It only has the 2nd person singular and 2nd person plural. Look at me. Help me, please.
