Tautology is a term referring to an action that although everyone tautology incur very little known that the technical name for the " voice Idiom "
It means, redundant statement, it is common for a person with little linguistic tact to result in simple phrases such as: I am going to go up, I am going to go down, they are completely unnecessary statements but given the conditions or custom, people may consider it useful to clarify ideas.
It is obvious to affirm questions as basic as an action as simple as saying " I saw it with my own eyes ", "Going up", "Going down", However, many will ask why is tautology so important?
A tautology lacks common sense, it is not considered entirely necessary, but it reaffirms an idea and also considers it as an assertion, since the fact of inferring in these idioms most of the time reinforces the veracity of the fact that is being treated. Although it is true that there are more ways to affirm, corroborate and highlight an action, most people choose to use the tautology more as an involuntary action than as a logical one, instead of making it known that it is being done to strengthen the idea.
For many it is uncomfortable, even to the point of seeing it as a mistake in people who use this feature.
There are two other terms related to tautology that indicate that there are two ways of asserting redundantly. When exactly the word to be reaffirmed is repeated " Yes, because Yes ", "No and No", "I am what I am", "You are what you are", it is called the truism truth, and the other is the Pleonasm, which describes the situations already mentioned above when reaffirming with the most obvious.
Specifically, tautology is an idiom, a product of the lack of understanding of the word, good attention to what is said, the practice of logic when speaking, good posture and security when speaking will help the correction of something that is not bad, not wrong, but not necessary.
It is also considered a form of tautology when a person asks a question and is answered with the same question, in this case it is a shared redundancy but as common as the statements that have been previously exposed.
