noun, masculine/ʒaʁ.ɡɔ̃/plural: jargons
jargon, specialised or unintelligible language
Related: jargonner, jargonnesque
Inherited from Old French jargon, gargun ("cheeping of birds"), from a root *garg expressing the sound of the throat or referring to it. See gargouille, gargariser, gargoter. The initial /ʒ/ sound comes from a softening of /g/, as in jambe.
