Best practice
When describing something that is utilized to a great extent, prefer the grammatically correct phrase "extensively used" or alternatives like "widely used".
Common error
Avoid using "extensive" as an adverb. "Extensive" is an adjective, so it cannot directly modify the verb "used". Always use the adverbial form "extensively" to correctly modify the verb.
