'predictably-advancing' originates from the combination of 'predictably' and 'advancing', where 'predictably' is derived from 'predict', meaning 'to foresee', and 'advancing' from 'advance', meaning 'to move forward'.

'predictably' changed from the Latin word 'praedicere', and 'advancing' from the Old French word 'avancer', eventually forming the modern English term 'predictably-advancing'.

Initially, 'predictably' meant 'able to be predicted', and 'advancing' meant 'moving forward', which together evolved into the current meaning of 'progressing in a foreseeable manner'.
