'PR' is an abbreviation of 'public relations', which originates from the Latin word 'publicus', meaning 'of the people', and 'relationem', meaning 'a bringing back'.

'Public relations' evolved from the Latin 'relationem' to the modern English term 'relations', and 'publicus' to 'public'.

Initially, it referred to the act of relating to the public, but now it encompasses a broader range of activities aimed at managing public perception.
