Many jargon terms pass into the standard language. Jargon spreads from a narrow group until it is used by a large segment of the population, similar to slang. Eventually, it may lose its special status as either jargon or slang and gain entrance into the respectable circle of formal usage. This is true of the now ordinary French word meaning ‘head’ tête, which was once a slang word derived from the Latin testa, which meant ‘earthen pot’.
