'promotion' originates from Latin, specifically the word 'promotio,' where 'pro-' meant 'forward' and 'movere' meant 'to move.'

'promotio' transformed into the Old French word 'promotion,' and eventually became the modern English word 'promotion' through Middle English.

Initially, it meant 'to move forward or advance,' but over time it evolved into its current meanings related to advancement in rank, encouragement, and marketing activities.
