'infrequently-bestowed' originates from the combination of 'infrequently' and 'bestowed'. 'Infrequently' comes from Latin 'in-' meaning 'not' and 'frequentia' meaning 'crowd or frequency'. 'Bestowed' comes from Middle English 'bistowen', from Old English 'bestōwian', meaning 'to place or give'.

'Infrequently' changed from the Latin 'infrequentia' to the modern English 'infrequent'. 'Bestowed' evolved from Old English 'bestōwian' to Middle English 'bistowen', eventually becoming 'bestowed'.

Initially, 'bestowed' meant 'to place or give', and 'infrequently' meant 'not often'. The combined term 'infrequently-bestowed' retains the original meanings, emphasizing rarity in giving.
