'relational' originates from the Latin word 'relatio', where 'relatio' meant 'a bringing back' or 'a report'.

'relatio' transformed into the Old French word 'relacion', and eventually became the modern English word 'relation', from which 'relational' is derived.

Initially, it meant 'a bringing back or report', but over time it evolved into its current meaning of 'concerning connections'.
