The Imperative is one of the moods you might find hard to use when learning Spanish as it doesn’t always have the same used as in English. I would advice you not to try to translate literally the sentences where you might find it as the meaning might sound a “bite” rude to you as an English speaker but, believe me, its meaning is not as hard as it may sound, it is softener.
The imperative mood is used to give orders, commands and makes requests.
To conjugate it you will need to know some other tenses such as the Simple Present of Indicative and Subjunctive, and it conjugates on the following persons only: tú, él, ella, usted, nosotros, vosotros, ellos, ellas, ustedes.
I´m going to write the reference to these two tenses so that you can check the information that will follow in this post.
