inflame

The word inflame carries a powerful image: to set something on fire. While it literally means to cause something to burn, its figurative meanings are far more common today. To inflame something means to excite strong feelings—often negative ones like anger, hatred, or passion. A controversial article might inflame debate online, sparking heated arguments and division. Conversely, a charismatic leader can inflame the hearts of their followers with inspiring rhetoric.

However, inflame also describes a physical process. When a wound or body part is inflamed, it becomes red, swollen, hot, and painful; these are signs that the body is reacting to injury or infection. Similarly, conditions like arthritis can cause joints to become inflamed. In this context, the word means to make a condition worse or to trigger that painful reaction.

The word usually suggests intensity. It is not just about change, but about making something stronger in a way that feels hot, forceful, or hard to control. Whether it refers to emotions, physical conditions, arguments, or even a literal fire, the core idea remains the same: to inflame is to make something burn more fiercely, either in reality or in a figurative sense.
