2. The language of a particular group which is associated with similar activities; for example, the language of street gangs or criminals: Before the fight started, the gangs were yelling out their peculiar argots, or special slang terms, to communicate with their fellow gang members as a kind of code.
The teenagers were confusing their teachers by using special argots in their written reports.
The British have their argots and Americans usually have completely different argots which often results in a lack of understanding of the argots of the two cultures.
Sometimes it can be very difficult to understand the various argots of scientists, lawyers, and even medical professionals.
3. Etymology: about 1860, from French argot, "the jargon of Paris rogues and thieves"; earlier "the company of beggars"; from Middle French (the French language as written and spoken about 1400 to 1600), "a group of beggars", otherwise, the origin of the term is unknown.
