What is the term for causing someone to become extremely angry?

The term "incite" specifically refers to the act of provoking or stirring up strong emotions in someone, particularly anger. When one incites someone, they ignite a reaction that may lead to heightened feelings of rage or aggression. This term is often used in contexts involving robust emotional responses, making it the appropriate choice for describing actions that lead to extreme anger.

In contrast, the other terms do not relate to causing anger. "Incoherent" describes something that is unclear or lacking logical connection, which does not pertain to emotional provocation. "Impair" refers to weakening or damaging something, usually relating to function or ability, rather than stirring emotional responses. Lastly, "incredulous" means unable or unwilling to believe something, which is also unrelated to the act of causing anger. Thus, "incite" stands out as the term that accurately defines the action of provoking intense anger in someone.
