Which mistakes are NOT highlighted by the spell checker in a word-processing document?

Answer 1

The spell checker feature in a word processor program will detect many spelling mistakes, but spelling mistakes that are actually valid words will not be noted. Also, most spell checkers will give you false errors for valid alternative spellings of words, because whoever wrote the software chose just one correct way, when there are actually at least two correct ways to spell several words. Also, the spell check might offer you a "correct" spelling that isn't correct at all in the context of your document because the software can't tell what you meant, so another word that is similarly spelled but completely wrong for your document might be offered as a "correction."

You also won't see errors pop up for other writing problems, like poor organization or repetitive language.

Another type of mistake that is not highlighted by the spell checker in a word processing document is the use of incorrect grammar, although some software offers grammar checking as well. Grammar checking, of course, has its own problems, which are much worse than spell check's problems.

Answer 2

A spell checker will find spelling errors in a word processing document. It will not find words that are used incorrectly in a sentence.
