'infrequently-examined' originates from the combination of 'infrequent' and 'examine', where 'infrequent' means 'not occurring often' and 'examine' means 'to inspect or scrutinize'.

'Infrequent' comes from the Latin word 'infrequens', and 'examine' comes from the Latin 'examinare'.

Initially, 'infrequent' meant 'not crowded' and 'examine' meant 'to weigh or test'. Over time, they evolved to mean 'not often' and 'to inspect', respectively.
