Other forms: inflamed, inflaming, inflames
To inflame is to make a feeling or a wound worse. Inflame tensions, an inflamed joint, inflame public opinion.
The medical sense is technical and the political one is a warning: language that inflames a situation makes violence likelier, which is why the word appears in every inquiry into a riot. Both come from the same image of setting something alight.
