Tending to duplicate or create copies; involving repetition of the same thing.
From 'duplication' with the suffix '-ive', which creates adjectives meaning 'tending to' or 'having the quality of'. The root remains the Latin 'duplicare' (to double).
Linguists find duplicative processes fascinating because many languages use them to show intensity—like English 'bye-bye' or 'fuzzy-wuzzy.' Some languages multiply meaning through deliberate doubling!
