I’ve been falling behind with my updates of SF words in the OED, I fear. This quarter’s update (for those of you not keeping score at home, the OED is in the process of a complete revision, and publishes quarterly updates of new and revised entries which pretty much always makes for fascinating reading) doesn’t have much of SFnal interest — just two words by my count: clone and skinsuit.
clone, n. 2. a. Chiefly Science Fiction. Any member of a hypothetical population of artificially produced, identical people, aliens, etc. Also: a duplicate of a living person.
First citation is from Alan Toffler’s Future Shock (1977). Interestingly, none of the citations are from actual SF, although three of the citations are reviews or discussions of SF works.
skinsuit n. any of various types of (usually one-piece) suit made of elasticated material which fits tightly to the body, esp. one designed for a particular sport.
Note that this definition rolls up the SF sense of skinsuit (a tight-fitting spacesuit, often intended for short-term or emergency use) with the sporting sense (as in that garment that short-track speed skaters wear). Their first citation is from 1956in a diving context, which handily beatsBrave New Word”s 1971 citation from Keith Laumer’s Dinosaur Beach.
