Did You Know?

Combustible and "incombustible" are opposites but "flammable" and "inflammable" are synonyms. Why? The "in-" of "incombustible" is a common prefix meaning "not," but the "in-" of "inflammable" is a different prefix. "Inflammable," which dates back to 1605, descends from Latin inflammare ("to inflame"), itself from "in-" (here meaning "in" or "into") plus "flammare" ("to flame"). "Flammable" also comes from "flammare," but didn't enter English until 1813. In the early 20th century, firefighters worried that people might think inflammable meant "not able to catch fire," so they adopted "flammable" and "nonflammable" as official safety labels and encouraged their use to prevent confusion. In general use, "flammable" is now the preferred term for describing things that can catch fire, but "inflammable" is still occasionally used with that meaning as well.
