'conventionality' originates from the Latin word 'conventionem,' where 'con-' meant 'together' and 'venire' meant 'to come.'

'conventionem' transformed into the Old French word 'convention,' and eventually became the modern English word 'conventionality.'

Initially, it meant 'a coming together or agreement,' but over time it evolved into its current meaning of 'adherence to traditional norms or practices.'
