Knowing how to conjugate a particular verb, taking into account the peculiarities that are attributed to it, means, above all, to make good use of the language we speak. In doing so, make sure that the speeches we make will become adequate to the formal standard of language, as well as if will present it in a clear, precise and objective way, thus facilitating the understanding of the interlocutors with whom we establish contact.
Such conjugation concerns the fact that we have the ability to assign the grammatical person the verbal form that best suits him. In this sense, some of these forms, depending on the linguistic circumstance, originate, derive from others, such as the present of the subjunctive and of the forms related to the affirmative and negative imperative, which derive from present tense.
Thus, let us use the example of the verb to sing, which, once conjugated, makes such derivations noticeable. This is what we will see below:
