'negotiable' originates from Latin, specifically the word 'negotiabilis,' where 'negotiari' meant 'to carry on business.'

'negotiabilis' transformed into the French word 'négociable,' and eventually became the modern English word 'negotiable' through Middle English.

Initially, it meant 'able to be transacted or carried on,' but over time it evolved into its current meanings of 'open to discussion' and 'able to be traversed.'
