'affectional' originates from Latin, specifically the word 'affectio,' where 'affectio' meant 'a relation or disposition.'

'affectio' transformed into the Old French word 'affection,' and eventually became the modern English word 'affectional' through Middle English.

Initially, it meant 'a relation or disposition,' but over time it evolved into its current meaning of 'relating to affection or love.'
