revolutionary
Adjective[C] Countable
This term carries a high-energy charge, suggesting a total break from the past rather than a gradual improvement. When used in a technical or commercial sense, it implies a paradigm shift that renders previous methods obsolete, though it is frequently overused in marketing to exaggerate a product's novelty. In a political context, the word evokes images of upheaval, defiance, and the risky pursuit of a new social order. It suggests a level of intensity and systemic change that is far more aggressive than "reformist" or "progressive," which typically seek to fix a system from within.
A person who leads a revolt (the revolutionary).
