'deliberately' originates from Latin, specifically the word 'deliberatus,' where 'de-' meant 'down' and 'liberare' meant 'to weigh.' 'injured' originates from Latin, specifically the word 'injuria,' where 'in-' meant 'not' and 'jus' meant 'right.'

'deliberatus' transformed into the Old French word 'deliberer,' and eventually became the modern English word 'deliberate.' 'injuria' transformed into the Old French word 'injurie,' and eventually became the modern English word 'injure.'

Initially, 'deliberate' meant 'to weigh down or consider,' and 'injure' meant 'not right or unjust.' Over time, 'deliberate' evolved to mean 'intentional,' and 'injure' evolved to mean 'to harm or wound.'
