'parsimony' originates from Latin, specifically the word 'parsimonia,' where 'pars-' meant 'spare' or 'frugal.'

'parsimonia' transformed into the Old French word 'parsimoinie,' and eventually became the modern English word 'parsimony.'

Initially, it meant 'frugality or thriftiness,' but over time it evolved into its current meaning of 'extreme unwillingness to spend money.'
