Spell Check Guide: Beyond Autocorrect
Use spell check effectively for professional documents. What it catches, what it misses, and manual checks to always do.
What Spell Check Catches
Misspelled words: Standard dictionary-based spell check catches genuine misspellings — teh → the, recieve → receive, occured → occurred.
Capitalisation errors: Some tools flag "internet" vs "Internet", proper nouns.
Repeated words: "the the" repeated words are caught by most word processors.
What Spell Check Misses
Correctly spelled wrong words: Their/there/they're, your/you're, affect/effect, its/it's, to/too/two. All correct spellings — spell check does not know which you meant.
Names and technical terms: Company names, product names, personal names, and technical jargon are not in standard dictionaries and get flagged as errors. Add them to your custom dictionary.
Context-dependent errors: "I will meat you at the station" — meat is spelled correctly but is the wrong word. Only grammar check catches this.
Manual Proofreading Checklist
After spell check, always manually check:
□ Recipient's name spelled correctly
□ Numbers and dates are correct
□ Links work and go to the right place
□ Attachments are actually attached
□ CC and BCC recipients are correct
Proofreading Tip: Read Backwards
Reading text from last word to first forces you to evaluate each word in isolation rather than reading for meaning. Your brain cannot auto-correct errors when reading backwards, so misspellings and incorrect words become visible.
Frequently asked questions
What is the difference between spell check and grammar check?
Spell check looks for misspelled words. Grammar check analyses sentence structure, word usage in context, and style. Grammar check catches their/there confusion; spell check does not.
Why does spell check miss some errors?
Spell check only knows if a word exists in its dictionary — not whether it is the right word for the context. Their/there, your/you're, and affect/effect all pass spell check because both words are real.
