'infrequently-reviewed' originates from the combination of 'infrequent' and 'reviewed'. 'Infrequent' comes from Latin 'infrequens', meaning 'not frequent', and 'reviewed' is derived from 'review', which comes from the Old French 'reviure', meaning 'to see again'.

'infrequent' changed from the Latin word 'infrequens' and eventually became the modern English word 'infrequent'. 'Reviewed' evolved from the Old French 'reviure' to the modern English 'review'.

Initially, 'infrequent' meant 'not occurring often', and 'review' meant 'to see again'. Over time, 'infrequently-reviewed' evolved to mean 'not often examined or assessed'.
