Etymology

Origin of jargon1

First recorded in 1300–50; Middle English jargoun, from Middle French; Old French jargon, gargun, derivative of an unrecorded expressive base garg- designating the throat and its functions, as in gargle, gargoyle

Origin of jargon2

First recorded in 1760–70; from French, from Italian giargone, of uncertain origin; perhaps ultimately from Persian zargūn “gold-colored” ( cf. zircon ( def. )), equivalent to zar “gold” ( see also arsenic ( def. ), gold ( def. ), yellow ( def. )) + gūn “color”; alternatively, perhaps akin to Old French jacincte, also jacunces, jargonce jacinth ( def. )

Explanation

Jargon usually means the specialized language used by people in the same work or profession. Internet advertising jargon includes the terms "click throughs" and "page views." This noun can also refer to language that uses long sentences and hard words. If you say that someone's speech or writing is full of jargon, this means you don't approve of it and think it should be simplified. In Middle English, this word referred to chattering, so its origin is probably imitative: it echoes the sound of chatter or meaningless words.
