Here is another word choice dilemma for you: Flammable and Inflammable. If you look up definitions for the words, they read the same: Easily ignited and combustible. Inflammable (or inflame), while correct, is confusing because of the prefix “in.” Some words  are made negative with the “in” prefix (Inert, inglorious, inconceivable). Inflammable, however, means flammable. So which is correct?

While inflammable is a word, Grammar Cop strongly suggests you use flammable. For safety reasons, you don’t want anyone mistaking inflammable for un–flammable.
