'deliberately' originates from Latin, specifically the word 'deliberatus,' where 'de-' meant 'down' and 'liberare' meant 'to weigh or balance.' 'Chosen' comes from Old English 'ceosan,' meaning 'to select or decide.'

'deliberatus' transformed into the French word 'délibérer,' and eventually became the modern English word 'deliberate.' 'Ceosan' evolved into the Middle English 'chosen,' which is the past participle of 'choose.'

Initially, 'deliberate' meant 'to weigh or consider carefully,' and this meaning has largely remained the same in modern usage. 'Chosen' has consistently meant 'selected or picked.'
