A spell checker is an excellent tool, but it is not foolproof. For instance, if a misspelled word is also an English word, the spell checker will not catch it. I often see the following errors in my edits:
- “form” instead of “from”
- “expect” instead of “except”
- “leaning” instead of “learning”
- “trail” instead of “trial”
- “filed” instead of “field”
If any of these words pop up in your paper, it is worth having a quick check for their common misspellings.
