The argument is a term that comes from the Latin "argumentum" and is simply the way in which the person reasons to demonstrate or convince another or others of what they affirm or deny. From this came what is known as the theory of argumentation, which is an interdisciplinary study of the way in which conclusions are obtained through logic.
Argument is an expression that can be oral or written of reasoning. It also allows to justify something to obtain two possible endings: persuade the subject to do what is desired or transmit a true content with foundations and bases of understanding.
The argument is based on debate and negotiation between the parties involved. It is very common for people to use this tool to protect their interests with a rational dialogue and thus each one defends their ideas without dismissing those of another. It is very common to see this type of debate in trials to approve or reject the validity of the evidence or evidence presented against the accused. The argumentation studies the different rationalizations made by an individual to justify decisions that at the beginning could have been made in a somewhat irrational way.
The arguments must have coherence and be consistent without contradictions, since then they would not be arguments. In ancient times using argumentation was an object of interest in the art of speaking and writing persuasively. Nowadays the argumentation has taken an important boom due to the mass media given the impact it has on society. A clear example of this is the advertising or political thought speeches.
An argument is not just the assertion of some opinions, nor is it simply a dispute. They are attempts to support opinions with reasons. Once the subject has been concluded, it is explained based on the reasons and that is where it is defended through the arguments.
For a good argumentation there must be a context, which will be the basis to convince the other of your idea. Also, the context determines the linguistic conventions that both use. When the context in which the argument takes place is not common to its participants, someone can easily use words that are annoying or aggravating to others.
