'discussion-based' originates from the English word 'discussion,' which comes from the Latin 'discussio,' meaning 'examination' or 'investigation,' combined with 'based,' from the Old French 'bastir,' meaning 'to build.'

'discussion' evolved from the Latin 'discussio' to the Old French 'discussion,' and eventually became the modern English word 'discussion.' 'Based' transformed from the Old French 'bastir' to the modern English 'base.'

Initially, 'discussion' meant 'examination' or 'investigation,' but over time it evolved to mean 'a conversation or debate about a specific topic.'
