The word "nonsmoking" is a combination of the prefix "non-" meaning "not" and the verb "smoking" which derives from the Old English word "smocian". "Smocian" itself is believed to have originated from the Proto-Germanic word "smokōną" or "smukkōną", which meant "to emit smoke" or "to burn". Over time, "smocian" evolved into "smoke" in Middle English, and the modern form "smoking" also emerged.
