[UPDATE: This post is out of date. Please see my static page Scientific word list for spell-checkers/spelling dictionaries for up-to-date information about these scientific word lists. I mean, the links to the files custom_scientific_US.txt and custom_scientific_UK.txt below will take you to the updated files, because I just replaced the old files with the new files without changing the names, but the information about them is out of date. The non-dialect-specific file custom_scientific.txt is still the same, but that’s because I haven’t added anything to it, whereas I’ve added hundreds of thousands of entries to the other two.]
It is amazing how hard it is to find any list, much less a comprehensive one, of scientific terms to add to spelling dictionaries, such as those of Microsoft Word, OpenOffice, LibreOffice, etc. Well, I decided to remedy that by putting my lists online for all to download. I’ve accumulated thousands of terms in my Microsoft Word custom dictionary over my career as a scientific editor, and I added thousands more from such sites as Rawge’s Scientific Names Spell Checker Dictionary, which actually includes several lists of various types of animals; this list of European species names; and my editing company’s house list.
One note about UK/US spellings: the file “custom_scientific” below should be rid of all UK- and US-specific spellings, such as hem-/haem-, -iter/-itre, estr-/oestr-, -ize/-ise, etc. If you find any that don’t belong, or any other typos, please please please tell me in the comments.
I’ve included three files:
custom_scientific.txt (49,552 entries): the words from the above-mentioned sources, minus UK-/US-specific spellings.
custom_scientific+US.txt (58,775 entries): custom_scientific plus all of the entries in my Microsoft Word US English spell-check dictionary that I’ve accumulated over the years. (This includes many AmE-specific spellings but also several thousand terms that have only one spelling and which therefore would belong in custom_scientific above, but I haven’t gotten around to copying and pasting the latter subset there. It also includes several foreign names, geographic locations, and words related to research institutes and departments, such as Recherche and Tecnología, because I encounter them often enough that it was preferable to add them instead of clicking “Ignore all” every damn time and/or because they aren’t similar to any mistyped English word that would need flagging and correcting.)
custom_scientific+UK.txt (52,200 entries): same as previous paragraph but for BrE.
Finally, please download these, copy them, share them, spread them, host them, correct them, add to them, and use them! The more such lists exist on the internet (and, eventually, in software spell-checkers’ native files), the better off every scientific writer, editor, researcher, and student is.
