Negative Prefixes to HOME PAGEwhat is the difference please between flammable and inflammable? There is no difference in meaning and little or no difference in use. Chemicals, gases or cloth materials that are flammable / inflammable catch fire and burn easily. Perhaps, in usage, cloth materials are usually described as inflammable. So we might say: 'The material from which these car seats are made is highly inflammable. And conversely, certain gases or chemicals may be thought of as flammable. So we might say: 'Aircraft fuel is highly flammable'. But there are no hard and fast patterns. All this is somewhat strange, because usually when we add a prefix such as in- or un- or dis- to the beginning of adjectives, adverbs and verbs, we give them the opposite meaning. Try this activity. Draw half a dozen columns on a large piece of paper and insert a prefix heading in each column. Perhaps leave one or two columns empty for new prefix headings as they occur to you.
