Which sense of radical is 'new and different'?

• A. Extreme; drastic
• B. Supporting drastic changes
• C. Very important
• D. New and different

Answer: (D)

Understanding the different senses of radical helps you pick the one that means new and different. When radical is used to describe ideas, methods, or changes, it signals something innovative that breaks with what has come before—revolutionary, ground-breaking, or new in its approach. That sense fits the prompt because it directly conveys novelty and a departure from the status quo, rather than simply indicating degree or intensity.

While radical can also mean extreme or drastic, that sense focuses on how much something changes rather than on the novelty of the change itself. It’s not about being very important, either, and describing someone who supports drastic changes talks about a stance more than a descriptive sense of the word. So the best fit for “new and different” is the innovative usage of radical.
