'post-analysis' originates from the prefix 'post-' meaning 'after' and the word 'analysis' from Greek 'analusis,' where 'ana-' meant 'up' and 'lusis' meant 'loosening.'

'analusis' transformed into the Latin word 'analysis,' and eventually became the modern English word 'analysis.' The prefix 'post-' was added to denote 'after analysis.'

Initially, 'analysis' meant 'a detailed examination,' and with the prefix 'post-,' it evolved to mean 'examination after an event.'
