Below is a massive list of sci fi words - that is, words related to sci fi. The top 4 are: literature, hugo award, fantasy and science. You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. The words at the top of the list are the ones most associated with sci fi, and as you go down the relatedness becomes more slight. By default, the words are sorted by relevance/relatedness, but you can also get the most common sci fi terms by using the menu below, and there's also the option to sort the words alphabetically so you can get sci fi words starting with a particular letter. You can also filter the word list so it only shows words that are also related to another word of your choosing. So for example, you could enter "literature" and click "filter", and it'd give you words that are related to sci fi and literature.

You can highlight the terms by the frequency with which they occur in the written English language using the menu below. The frequency data is extracted from the English Wikipedia corpus, and updated regularly. If you just care about the words' direct semantic similarity to sci fi, then there's probably no need for this.

There are already a bunch of websites on the net that help you find synonyms for various words, but only a handful that help you find related, or even loosely associated words. So although you might see some synonyms of sci fi in the list below, many of the words below will have other relationships with sci fi - you could see a word with the exact opposite meaning in the word list, for example. So it's the sort of list that would be useful for helping you build a sci fi vocabulary list, or just a general sci fi word list for whatever purpose, but it's not necessarily going to be useful if you're looking for words that mean the same thing as sci fi (though it still might be handy for that).

If you're looking for names related to sci fi (e.g. business names, or pet names), this page might help you come up with ideas.

If your pet/blog/etc. has something to do with sci fi, then it's obviously a good idea to use concepts or words to do with sci fi.

That's about all the sci fi related words we've got! I hope this list of sci fi terms was useful to you in some way or another. The words down here at the bottom of the list will be in some way associated with sci fi, but perhaps tenuously (if you've currenly got it sorted by relevance, that is). If you have any feedback for the site, please share it here, but please note this is only a hobby project, so I may not be able to make regular updates to the site. Have a nice day! 🐖
