'undramatic' originates from the prefix 'un-' meaning 'not' and the word 'dramatic' which comes from the Greek word 'dramatikos', meaning 'pertaining to drama'.

'dramatikos' transformed into the Latin word 'dramaticus', and eventually became the modern English word 'dramatic', with 'un-' added to form 'undramatic'.

Initially, 'dramatic' meant 'pertaining to drama', and 'undramatic' has consistently meant 'not pertaining to drama'.
