'disturb' originates from Latin, specifically the word 'disturbare,' where 'dis-' meant 'apart' and 'turbare' meant 'to throw into disorder.'

'disturbare' transformed into the Old French word 'destorber,' and eventually became the modern English word 'disturb' through Middle English.

Initially, it meant 'to throw into disorder,' but over time it evolved into its current meaning of 'to interrupt or upset.'
