'reallocative' originates from the verb 'reallocate,' which is derived from the prefix 're-' meaning 'again' and the verb 'allocate,' which comes from Latin 'allocare,' meaning 'to assign.'

'reallocate' evolved from the Latin word 'allocare,' which transformed into the Old French 'alouer,' and eventually became the modern English word 'allocate.'

Initially, 'allocate' meant 'to assign or allot,' and with the prefix 're-,' 'reallocate' evolved to mean 'to assign again or differently.'
