Given the dynamic character that guides the language - seen as a strictly social entity -, behold, we come across one of the elements that also integrate the word formation process, as so many others. Remember the derivation and the composition?
Well, our goal is to emphasize the vocabulary abbreviation, which literally consists of the elimination of a segment - referring to a certain word -, in order to obtain a more reduced form of it, without changing the sense. This process is conceived as largely productive in reducing very long words, such as:

And it is precisely because of this aspect linked to colloquialism that we can see marks impregnated with meaning, once represented by different feelings, sometimes representing affection, sometimes representing contempt, mockery, prejudice, among others.
