'expectedly-finished' is a compound word formed from 'expectedly' and 'finished'. 'Expectedly' originates from the Latin word 'expectare', meaning 'to look out for', and 'finished' comes from the Latin 'finire', meaning 'to end'.

'expectedly' evolved from the Old French 'expecter', and 'finished' from the Old French 'finir'. The combination of these words into 'expectedly-finished' is a modern English construct.

Initially, 'expectedly' meant 'in a manner that was looked out for', and 'finished' meant 'ended'. Together, they convey the idea of something ending as anticipated.
