'pro-incarceration' originates from the prefix 'pro-' meaning 'in favor of' and the word 'incarceration,' which comes from Latin 'incarcerare,' meaning 'to imprison.'

'Incarceration' evolved from the Latin 'incarcerare' through Old French 'incarcérer' and eventually became the modern English word 'incarceration.'

Initially, 'incarceration' meant 'to imprison,' and this meaning has largely remained the same in modern usage.
