'insertion' originates from Latin, specifically the word 'insertionem,' where 'in-' meant 'into' and 'serere' meant 'to join or bind.'

'insertionem' transformed into the French word 'insertion,' and eventually became the modern English word 'insertion' through Middle English.

Initially, it meant 'to join or bind into,' but over time it evolved into its current meaning of 'the act of putting something inside something else.'
