'infrequently-awarded' originates from the combination of 'infrequently' and 'awarded'. 'Infrequently' comes from Latin 'in-' meaning 'not' and 'frequentare' meaning 'to visit often'. 'Awarded' comes from Old French 'eswarder', meaning 'to judge'.

'Infrequently' evolved from the Latin 'infrequentia', while 'awarded' evolved from the Old French 'eswarder', eventually forming the modern English compound 'infrequently-awarded'.

Initially, 'infrequently' meant 'not often', and 'awarded' meant 'to judge or bestow'. The compound 'infrequently-awarded' retains the meaning of being rarely given.
