'hypersensitive' originates from the Greek prefix 'hyper-' meaning 'over' or 'beyond' and the Latin word 'sensitive,' which means 'capable of feeling or perceiving.'

'hypersensitive' evolved from the combination of the Greek prefix 'hyper-' and the Latin word 'sensitive,' forming the modern English word 'hypersensitive.'

Initially, it meant 'overly sensitive to stimuli,' and this meaning has largely remained the same in modern usage.
