intensifier

In linguistics, this term describes words like "extremely" or "quite" that modify the degree of an adjective or adverb. These words do not change the core meaning of the target word but instead shift its magnitude or emotional weight on a scale of intensity. In a chemical or technical sense, the term refers to a physical agent that amplifies a reaction. This usage is distinct from a catalyst, as an intensifier specifically focuses on increasing the potency or strength of the resulting effect rather than just the speed of the process.
