The Spanish word 'jerigonza', meaning 'jargon' or 'gibberish', has an interesting journey from Latin through Occitan. It begins with the Latin word 'gurges', which meant 'whirlpool' or 'throat'. This evolved into the Occitan word 'gergons', which was used to describe both bird warbling and incomprehensible speech. The connection between a whirlpool/throat and unintelligible speech makes intuitive sense - just as a whirlpool swirls and churns water in a confusing way, unclear speech seems to swirl and become muddled in the throat. From Occitan, the word finally developed into Spanish 'jerigonza', maintaining the sense of confused or unintelligible speech.

While 'jerigonza' itself is a relatively unique word in Spanish, you might encounter the related term 'jerga', which also means 'jargon' or 'slang' and shares a similar etymological background of referring to confused or specialized speech that's difficult for outsiders to understand.

While English doesn't have any direct cognates of 'jerigonza', we do have some words that capture similar concepts about confused speech. The word 'jargon' itself, though from a different etymological root, serves a very similar function to 'jerigonza' in describing specialized or unintelligible language. Another interesting parallel is 'gargle', which comes from the same Latin root 'gurges' (meaning throat or whirlpool) that gave us 'jerigonza', though it developed to describe the act of swishing liquid in one's throat rather than confused speech.
