'unrealistically' originates from 'unrealistic,' which is derived from 'un-' meaning 'not' and 'realistic' meaning 'based on reality.' 'Changed' comes from Old French 'changier,' meaning 'to alter or exchange.'

'unrealistic' evolved from the combination of 'un-' and 'realistic,' while 'changed' transformed from Old French 'changier' to Middle English 'chaungen,' eventually becoming 'change.'

Initially, 'unrealistic' meant 'not based on reality,' and 'changed' meant 'altered.' The combined term 'unrealistically-changed' emphasizes impractical alterations.
