'predictably-led' originates from the combination of 'predictably' and 'led'. 'Predictably' comes from 'predict', which originates from Latin 'praedicere', where 'prae-' meant 'before' and 'dicere' meant 'to say'. 'Led' is the past participle of 'lead', which comes from Old English 'lǣdan', meaning 'to guide'.

'Predictably' evolved from the Latin 'praedicere' through Middle English 'predicten', and 'led' evolved from Old English 'lǣdan'.

Initially, 'predict' meant 'to say before', and 'lead' meant 'to guide'. Over time, 'predictably-led' evolved to mean being guided in an expected manner.
