'expectedly-taken' is a compound word formed from 'expectedly' and 'taken'. 'Expectedly' originates from the Latin word 'expectare', meaning 'to look out for', and 'taken' is the past participle of 'take', which comes from the Old English 'tacan', meaning 'to seize'.

'expectedly' evolved from the Latin 'expectare' through Old French 'expecter', and 'taken' evolved from the Old English 'tacan'. The combination of these words into 'expectedly-taken' is a modern English formation.

Initially, 'expectedly' meant 'in a manner that is anticipated', and 'taken' meant 'seized or occupied'. The combination retains these meanings in modern usage.
