'infrequently-granted' originates from the combination of 'infrequent' and 'grant,' where 'infrequent' means 'not occurring often' and 'grant' means 'to give or allow.'

'infrequent' changed from the Latin word 'infrequens,' and 'grant' from the Old French word 'graanter,' eventually becoming the modern English word 'grant.'

Initially, 'infrequent' meant 'not crowded' and 'grant' meant 'to agree to,' but over time, they evolved into their current meanings of 'not often' and 'to give or allow,' respectively.
