'accommodative' originates from Latin, specifically the word 'accommodativus,' where 'ad-' meant 'to' and 'commodare' meant 'make fit or suitable.'

'accommodativus' transformed into the French word 'accommodatif,' and eventually became the modern English word 'accommodative' through Middle English.

Initially, it meant 'to make fit or suitable,' but over time it evolved into its current meaning of 'willing to fit in with someone's wishes or needs.'
