'addleplot' originates from Middle English, specifically the word 'addle,' where 'addle' meant 'confused' and 'plot' referred to a 'plan or scheme.'

'addle' transformed from the Old English word 'adlian,' meaning 'to become rotten,' and eventually became part of the compound 'addleplot' in modern English.

Initially, 'addle' meant 'to become rotten,' but over time it evolved into its current meaning of 'confused or muddled.'
