Technical jargon: What is Lingo?

Suddenly everyone is speaking the same lingo, or not: in companies, in departments, projects or teams, the word is heard more and more often. It has been around for a long time among rappers, gangstas and programmers, but its use usually had something disrespectful about it. Today, lingo is socially acceptable and, according to the Duden dictionary, actually stands for gibberish, technical jargon or foreign language. In everyday life, however, it increasingly marks the boundaries of one's own linguistic world. "We just speak the same lingo" or "They just speak a different lingo" helps individuals find their way through the gender-neutral and politically correct language jungle and prevents them from having to learn legalese as well: the lingo of lawyers.
