Sci-Fi is the nickname for science fiction
'Sci-fi' is
a nick-name for science fiction. It is not the one used by people who know and love the genre. People who actually know science and like science fiction call it 'SF'. Rather, it tends to be used by people who think of science fiction stories as just like westerns but with rayguns and spaceships.
As a result of this difference in usage, Isaac Asimov suggested that the two terms should be specialised: 'SF' refers to the half of science fiction which attempts to explore the reactions of people and social institutions to fictitious environments and events suggested by science and technological change.; 'Sci-fi' refers to the half of science fiction that dresses up westerns, fantasy, and seafaring stories in futuristic fancy dress.
Except that Asimov was rude about it.
Asimov's suggestion has caught on. 'SF' is the shibboleth of the
soi-disant science fiction purists, who consider anything labelled 'Sci-fi' to be describing itself as ignorant commercial pap. Their position is smug and elitist: but the usage is established. The fact that you did not understand it until now is not particularly significant, unless you choose to make it so.
Me, I think that there is good SF and bad SF, good sci-fi and bad sci-fi, and no particular credit or discredit in preferring one over the other. But insisting that they are the same, especially out of resentment at the condescending attitude of an unmmannerly slob, is simply wrong-headed.
