'carelessly-verified' originates from the combination of 'careless' and 'verify', where 'careless' means 'without care' and 'verify' means 'to confirm or check'.

'careless' comes from Old English 'carleas', meaning 'free from care', and 'verify' comes from Old French 'verifier', meaning 'to confirm'.

Initially, 'careless' meant 'free from care', but over time it evolved to mean 'lacking attention'. 'Verify' has largely retained its original meaning of 'to confirm'.
