Vehementen
Vehementen is a term often used to describe a strong, forceful, or passionate expression of opinion, emotion, or action. It implies a high degree of intensity and conviction. This word can be applied to various contexts, such as a vehement denial, a vehement protest, or vehement opposition to a particular idea or policy. The vehemence of a statement or action suggests that the speaker or actor feels very strongly about the subject at hand, often to the point of being intense or aggressive in their delivery.
In discourse, a vehement argument might be characterized by loud speech, emphatic gestures, and unwavering certainty.
