'frequently-confirmed' originates from the combination of 'frequent' and 'confirm', where 'frequent' means 'occurring often' and 'confirm' means 'to establish the truth or correctness of something'.

'frequent' and 'confirm' were combined to form the modern English term 'frequently-confirmed'.

Initially, 'confirm' meant 'to establish the truth', and 'frequent' meant 'occurring often'. Together, they evolved to describe something that is often verified.
