'disrespect' originates from Latin, specifically the word 'disrespectus', where 'dis-' meant 'apart' and 'respectus' meant 'regard'.

'disrespectus' transformed into the French word 'desrespect', and eventually became the modern English word 'disrespect' through Middle English.

Initially, it meant 'to regard apart or differently', but over time it evolved into its current meaning of 'to show a lack of respect'.
