'expertly-edited' originates from the combination of 'expertly' and 'edited', where 'expertly' is derived from 'expert', meaning 'a person with a high level of knowledge or skill', and 'edited' is the past participle of 'edit', meaning 'to prepare written material for publication'.

'expertly' changed from the Old French word 'expert', and 'edited' evolved from the Latin word 'editus', eventually forming the modern English term 'expertly-edited'.

Initially, 'expertly' meant 'with skill or knowledge', and 'edited' meant 'prepared for publication'. Together, they evolved to mean 'skillfully revised by an expert'.
