'equitably' originates from Latin, specifically the word 'aequitas,' where 'aequi-' meant 'equal' and '-tas' meant 'state or condition.' 'Cancelled' originates from Latin, specifically the word 'cancellare,' where 'cancell-' meant 'to make a lattice of lines.'

'Aequitas' transformed into the Old French word 'equité,' and eventually became the modern English word 'equity.' 'Cancellare' transformed into the Old French word 'canceller,' and eventually became the modern English word 'cancel.'

Initially, 'equitably' meant 'in an equal manner,' but over time it evolved into its current meaning of 'fairly.' 'Cancelled' initially meant 'to cross out with lines,' but now means 'to annul or invalidate.'
