Stefnist or stfnist (or even stfist) an archaic term derived from stf, an abbreviation for scientifiction, was Jack Speer's attempt at a replacement for the often misunderstood fan, but it didn't take. It's still used sometimes, especially by faanish fans, to refer to people who take a serious or scholarly (but not necessarily sercon) interest in science fiction, and who may or may not be part of the microcosm, or as an avoidance.
A long form is scientifictionist.
|From Fancyclopedia 1 ca 1944
|(Speer) - A suggested substitute for the word "fan", which has been favorably received. At this writing, however, a full vocabulary on the root has not been worked out, nor is general acceptance certain.
