Answer 1

r u being sarcastic? xD

Answer 2

Spell check is a computer based program. Here is a list of problems that could happen:

1. The check could mistake your word for another.

2.  Certain words, like a difficult name, would not be in the dictionary, therefore causing an issue.

3. If you are typing in a different language, the spell check will correct in English.

Hope I helped! :D
