'expectedly-faulty' is a compound word formed from 'expectedly' and 'faulty'. 'Expectedly' originates from the Latin word 'expectare', meaning 'to look out for', and 'faulty' comes from the Old French 'faute', meaning 'mistake'.

'Expectedly' evolved from the Latin 'expectare' through Old French 'expecter', while 'faulty' transitioned from Old French 'faute' to Middle English 'faute', eventually becoming 'faulty'.

Initially, 'expectedly' meant 'to look out for', and 'faulty' meant 'mistake'. Over time, 'expectedly-faulty' came to mean 'anticipated to have defects'.
