What does inflame mean?
Inflame is a transitive verb that makes emotions, disputes, or situations more intensely heated, especially by provoking anger, resentment, or hostility. Its most familiar figurative use suggests a process of escalation: a comment inflames tensions, a dispute inflames opposing groups, or a decision inflames public opinion. Although the word can sound dramatic, it is widely used in news, political, and academic prose. Inflame also has literal and medical applications. A fire may be said to inflame nearby material, and inflamed tissue is tissue affected by inflammation. These meanings are related through the original idea of fire and heat, but modern usage most often concerns emotional or social intensity rather than combustion. The verb is commonly transitive and can carry a strongly negative connotation because its typical objects—anger, tensions, hatred, and hostility—are conflict-producing. Understanding both its figurative force and its more technical uses helps make “inflame” vivid without exaggerating its meaning.
