inflammatory

This word has two very different meanings depending on the context. When used in politics or social situations, it refers to emotions (anger). When used in medicine, it refers to the physical body. In a social context, 'inflammatory' is almost always negative. It describes speech or writing that is designed to make people fight or become upset. In a medical context, it is a neutral descriptive term. You will frequently see it paired with the prefix 'anti-' (as in 'anti-inflammatory') to describe medicines that stop swelling.
