'correlate' originates from Latin, specifically the word 'correlatus', where 'cor-' meant 'together' and 'relatus' meant 'brought back'.

'correlatus' transformed into the French word 'correlat', and eventually became the modern English word 'correlate' through Middle English.

Initially, it meant 'to bring together', but over time it evolved into its current meaning of 'having a mutual relationship'.
