'occasionally-reviewed' originates from the combination of 'occasionally' and 'reviewed'. 'Occasionally' comes from the Latin 'occasio', meaning 'a happening', and 'reviewed' comes from the Old French 'reviure', meaning 'to see again'.

'occasionally' evolved from the Latin 'occasio' through Old French 'occasion', and 'reviewed' evolved from Old French 'reviure' to Middle English 'revien'.

Initially, 'occasionally' meant 'a happening', and 'reviewed' meant 'to see again'. Over time, 'occasionally-reviewed' came to mean 'reviewed from time to time'.
