Etymologically this word comes from the Latin "imperativus" and is related to someone or something that has the power to command or dominate. Likewise, the imperative term is linked to the unjustifiable duty or requirement, that is, it has no justification for not doing it and if for any reason it is not obeyed, there will be no justification that excuses the fact of not doing it.
For example, when an individual does not go to an appointment with a relative due to some work imperative. On the other hand, there is the moral imperative that refers to all that commitment or duty required in some situations related to ethics. This leads us to the categorical imperative term, which is a term set by a German philosopher named Inmanuel Kant which links the categorical imperative term to moral duty, not stealing or not killing are examples of categorical imperatives validated by universal moral laws, established by the human mind to be fulfilled without any exception.

This mode is used in almost all the languages of the world, in the Spanish language the imperative is located in the fourth place of the finite grammatical modes and is adjacent to the indicative, subjunctive and conditional, it is a mode that does not have any profile or format for all the people or numbers, for example: "Get out of here" , "Let's go right now" , are some of the sentences that use this grammatical mode.
