'duplicable' originates from Latin, specifically the word 'duplicare,' where 'du-' meant 'two' and 'plicare' meant 'to fold.'

'duplicare' transformed into the French word 'dupliquer,' and eventually became the modern English word 'duplicate' through Middle English.

Initially, it meant 'to fold into two,' but over time it evolved into its current meaning of 'to make a copy of something.'
