Etymology:
It was originally known as chattering or gibberish. Old French used jargon as “a chattering” and “language speech”. Along with the latin word garrire: to chatter. In the 1640s, it was known as “mixed speech”. Then in the 1650s, it developed into “a mode of speech with unfamiliar terms”. Middle English converted the French word “Jargounen” to “chatter”.
