'solvable' originates from Latin, specifically the word 'solvere,' where 'solv-' meant 'to loosen or untie.'

'solvere' transformed into the French word 'solvable,' and eventually became the modern English word 'solvable' through Middle English.

Initially, it meant 'to loosen or untie,' but over time it evolved into its current meaning of 'capable of being solved.'
