'ever-changing' originates from the combination of 'ever,' meaning 'always,' and 'changing,' the present participle of 'change,' meaning 'to make or become different.'

'ever-changing' evolved from the Old English word 'æfre' meaning 'always' and the Middle English 'chaungen,' which eventually became the modern English 'change.'

Initially, it meant 'always in the process of change,' and this meaning has largely remained the same in modern usage.
