'congenial' originates from Latin, specifically the word 'congenialis,' where 'con-' meant 'together' and 'genialis' meant 'of birth or kind.'

'congenialis' transformed into the French word 'congénial,' and eventually became the modern English word 'congenial' through Middle English.

Initially, it meant 'of the same kind or nature,' but over time it evolved into its current meaning of 'pleasant and agreeable.'
