Which word describes a process of making someone exceedingly angry?

The term "incense" in this context refers to the act of causing someone to become extremely angry. When you incense someone, you provoke or irritate them to the point where they feel considerable anger or rage. This verb specifically conveys a strong emotional reaction, highlighting the intensity of the anger being provoked.

The other options do not align with the meaning of inciting anger. For instance, "inaugurate" relates to the formal beginning of something, such as an official ceremony, while "inventive" pertains to creativity and originality in thinking or creating. "Intervene" means to come between or to disrupt a situation, but it does not carry the connotation of anger. Thus, "incense" is the clear choice for describing the act of making someone exceedingly angry.
