'infrequently-offered' originates from the combination of 'infrequent' and 'offer', where 'infrequent' means 'not occurring often' and 'offer' means 'to present or provide'.

'infrequent' changed from the Latin word 'infrequens' and 'offer' from the Latin word 'offere', eventually forming the modern English term 'infrequently-offered'.

Initially, 'infrequent' meant 'not crowded' and 'offer' meant 'to present', but over time it evolved into its current meaning of 'not often provided'.
