'recently-used' originates from the combination of 'recently' and 'used', where 'recently' is derived from the Latin word 'recens', meaning 'new' or 'fresh', and 'used' comes from the Old French 'user', meaning 'to employ'.

'recently' changed from the Latin word 'recens' to the Old French 'recent', and eventually became the modern English word 'recently'. 'Used' evolved from the Old French 'user' to the Middle English 'usen', and eventually became the modern English word 'used'.

Initially, 'recently' meant 'newly' or 'freshly', and 'used' meant 'employed'. Over time, 'recently-used' evolved to mean 'having been used in the recent past'.
