Etymology
The word 'jargon' entered English in the mid-14th century from Old French jargoun, meaning 'chattering, prattle, talk of birds'. The Old French term likely originated from a root imitative of the sound of chattering or twittering. This onomatopoeic origin connects to the modern sense of incomprehensible or specialized speech, which can sound like meaningless noise to an outsider. Over time, its meaning evolved from general idle talk to the specialized, often opaque vocabulary of a particular trade, profession, or group.
Analysis
The word is a simplex loanword from Old French. It is not productively formed from separable English morphemes.
