The relationship that exists between Tango and lunfardo is undeniable. You only have to go through the lyrics of tangos since its origins to find that the poets of the genre make an extensive use of lunfardo. But, what is really lunfardo? A language? A dialect? A prison slang? A vocabulary?

Because the use of lunfardo surpasses its appearance in the tango corpus, because it is a live element of the way of speaking of Buenos Aires I thought it was necessary to start to clarify what lunfardo is not, with the object of specifying further on what it is.
