'infrequently-produced' originates from the combination of 'infrequent' and 'produce', where 'infrequent' comes from Latin 'infrequens', meaning 'not crowded', and 'produce' from Latin 'producere', meaning 'to bring forth'.

'infrequent' changed from the Latin word 'infrequens' and 'produce' from 'producere', eventually forming the modern English term 'infrequently-produced'.

Initially, 'infrequent' meant 'not crowded', but over time it evolved to mean 'not occurring often', and 'produce' retained its meaning of 'to create or manufacture'.
