What does proliferative mean?
Proliferative means characterized by rapid multiplication, growth, or increase. In general contexts, it can describe a process that expands quickly, often in a way that seems excessive or difficult to control, as in a proliferative bureaucracy. In biology and medicine, the term more precisely refers to the multiplication of cells or tissues and is used in expressions involving proliferative growth, activity, and disease. The adjective is formal and specialized, so “rapidly increasing” or “multiplying” will often be clearer in ordinary conversation. It is related to the verb “proliferate,” meaning to multiply or spread rapidly, and to “prolific,” meaning highly productive or abundant.

Where does proliferative come from?
Proliferative was formed in the 19th century from “proliferate,” with the suffix “-ive” forming an adjective of the type associated with causing or displaying a particular action or quality. “Proliferate” ultimately derives from Latin “prolifer,” meaning prolific or fruitful, which was based on “proles,” an offspring or progeny. English “prolific” comes from the same Latin source and retains the related sense of producing abundant growth or results.
