'intentionally' originates from Latin, specifically the word 'intentio,' where 'in-' meant 'toward' and 'tendere' meant 'to stretch.' 'Supplied' comes from Latin 'supplere,' where 'sub-' meant 'under' and 'plere' meant 'to fill.'

'Intentio' transformed into the Old French word 'intencion,' and eventually became the modern English word 'intention.' 'Supplere' transformed into the Old French word 'souplir,' and eventually became the modern English word 'supply.'

Initially, 'intentionally' meant 'with intention or purpose,' and this meaning has largely remained the same in modern usage. 'Supplied' initially meant 'to fill up or complete,' and this meaning has largely remained the same in modern usage.
