In argumentative language, there are four basic forms: informative, which is used to communicate through statements that test whether something is true or false, as in a scientific text expressive, which expresses feelings and emotions, as in poems and directive, which helps influence the recipient's behavior by giving instructions and orders, like a boss. Finally, argumentative, is used when the intention is to convince or demonstrate an idea. About vagueness there are arguments that is not correct and this could affect the idea with examples that are not clear. On the other hand, about ambiguity there are expression or words that have more than one meaning. So the languaje is important to communicate the better way and make well arguments according the topic. 

Emotive language, also known as expressive language, focuses on the communicator, allowing them to express their reality and feelings; "It's a pleasure to be here." This can change negatively depending on the subject. According to fallacies, these argumentative keeps are unrelated to the conclusions. These are often the most common errors, as the premises used can be clearly related to the conclusion, creating an emotional or psychological effect on the audience.
