'astonishingly-changed' originates from the combination of 'astonishingly' and 'changed', where 'astonishingly' is derived from 'astonish', which comes from the Old French 'estoner', meaning 'to stun', and 'changed' is from the Old English 'cēosan', meaning 'to choose'.

'astonishingly' evolved from the Old French 'estoner', and 'changed' from the Old English 'cēosan', eventually forming the modern English compound 'astonishingly-changed'.

Initially, 'astonishingly' meant 'to stun or amaze', and 'changed' meant 'to choose or alter', evolving into the current meaning of 'surprisingly transformed'.
