'agendaless' originates from the English word 'agenda,' which comes from Latin 'agendum,' meaning 'something to be done,' combined with the suffix '-less,' indicating absence.

'agenda' transformed from the Latin 'agendum' into the English 'agenda,' and eventually became 'agendaless' by adding the suffix '-less.'

Initially, 'agenda' meant 'a list of things to be done,' but 'agendaless' evolved to mean 'without a specific agenda.'
