Yesterday the mail brought an SF magazine with a story of mine in a Slavic language I can't identify (Romanian? Czech?), and the June Asimov's with a story of mine that I can identify, "Call Back Yesterday." The title is from Shakespeare, that great repository for authors out of titular inspiration. This, combined with the paperwork for changing phone companies, got me thinking about words.
I am getting a different company for my "land line." Usually, names for things become shorter over time: "wireless connection" becomes "wi-fi," "ocean liner" becomes "liner." But my phone, which when I was a kid needed only one word because only one possible object could fit it, has now become a two-word descriptor, "land line," as other choices came into being (i.e., "cell phone"). Similarly, "egg donor mother" wasn't needed before surrogate pregnancy; before that, "mother" covered it all. And SF introduced the "Earth year" as a standard galactic time measure among planets with different rotation periods.
So what other current terms could, in the future, need additional descriptors when more choice is available? "Home body," when one can pour one's consciousness into a different body? In "Mirror Image," I used "human standard" to describe the symmetrical, four-limbed, air-breathing body that my characters return to after temporary sojourns in other, manufactured bodies suited to various planets' gravities and atmospheres. How about "starter body," on the lines of "starter marriage" -- also a term that didn't exist fifty years ago?
This could be a fun way to generate SF stories!
