'post-transaction' originates from the prefix 'post-' meaning 'after' and the word 'transaction' from Latin 'transactio', where 'trans-' meant 'across' and 'agere' meant 'to drive'.

'transaction' changed from the Latin word 'transactio' and eventually became the modern English word 'transaction'.

Initially, 'transaction' meant 'a driving through or across', but over time it evolved into its current meaning of 'a business deal or action'.
