'predictably-changed' originates from the combination of 'predictably' and 'changed'. 'Predictably' comes from 'predict', which originates from Latin 'praedicere', meaning 'to say beforehand'. 'Changed' is the past participle of 'change', which comes from Old French 'changier', meaning 'to alter'.

'predictably' evolved from the Latin 'praedicere' through Middle English 'predicten', and 'changed' evolved from Old French 'changier' to Middle English 'chaungen'.

Initially, 'predictably' meant 'in a manner that can be predicted', and 'changed' meant 'altered'. The combined form retains these meanings.
