Question

what are the advantages of spell check answer

Answer 1

Spell checkers are probably best for catching works that you mistype, especially if you write quickly. They'll also help with words you're not sure how to spell. One caveat: I'm wary of autocomplete and autocorrect features in spell-checking programs. It's too easy for them to "correct" a word you started to type to something you didn't intend. This especially true if you use a lot of less common words, foreign words or phrases, or jargon related to a specific profession or industry.
