What does inflammably mean?
Inflammably is an adverb meaning in a manner that is readily ignited, highly combustible, or, by extension, inclined to provoke anger and strong feeling. Its literal use describes materials or conditions that catch fire easily: dry brush may lie inflammably along a path, vulnerable to the smallest spark. In figurative writing, a person or statement may be described as inflammably provocative, suggesting language or conduct likely to stir up an intense response. The word is uncommon and has a formal, occasionally literary or technical register; in ordinary discussion, “flammably” is often clearer and more familiar. Inflammably derives from “inflammable,” an older English borrowing ultimately based on Latin words associated with fire and setting alight. Related English derivatives include “inflame,” “inflammation,” and “inflammatory.” Although it can initially be misunderstood, the adverb is useful in writing that needs to emphasize both rapid combustibility and figurative emotional heat.

Where does inflammably come from?
Inflammably was formed by adding the adverbial suffix -ly to inflammable. Inflammable entered English from French in the early modern period and ultimately derives from Latin inflammare, “to set on fire” or “inflame,” formed from in- and flamma, “flame.” English inflame, inflammation, and inflammatory continue the same Latin root.
