Using spell check in Word can prevent errors from appearing. Use the Word spell check function to produce error-free Word documents.
By default, Word automatically checks your document for spelling and grammar errors, so you may not even need to run a separate check. These errors are indicated by colored, wavy lines.
A misused word—also known as a contextual spelling error—occurs when a word is spelled correctly but used incorrectly. For example, if you used the phrase Deer Mr. Theodore at the beginning of a letter, deer would be a contextual spelling error. Deer is spelled correctly, but it is used incorrectly in the letter. The correct word is dear.
In previous versions of Word, grammar errors were marked with a green line, while contextual spelling errors were marked with a blue line.
