Misspelling words is not uncommon for anyone doing any writing work. In fact, you’d have to be a serious freak of sorts if you can pen an entire thousand words of copy without committing a single wrong spelling.
That’s What Grammar Checkers Are For
Sure, grammar checking software is supposed to catch all of those mistakes. However, with so many possible word combinations, a lot of awful typos can actually manage to slip through the cracks. A term like “publirc meeting” should easily get flagged, while “pubic meeting” will probably manage to stay (because both pubic and meeting are valid dictionary words).
Manual Spellcheck
You should be able to catch a mistake like the above by poring through the copy, proofing it word by word to turn up similar orthographic mishaps. It’s a tedious job, but it’s one you have to do. Even if you work with an editor who could catch the errant usage, fixing the spelling should leave them more time to work substantively on your copy, rather than devote it to dealing with things you can correct yourself.
Learning Spellcheck
If you’ve been shopping around for a good spellchecker, try to find one whose “database” of corrections you can add to. That way, when you catch yourself committing mistakes as the above (“pubic meeting”), you can simply instruct it to change the term to (“public meeting”), instead. It’s not a perfect system, but doing so can land you plenty of convenience for the future.
