Answer:
It changes it to an X
Explanation:
One of the best software for writing papers is Word. This is because it has the ability to detect spelling and grammar errors when this feature is being turned on. When using Word, if you make an error in your grammar or spelling, the software automatically changes the Spelling and Grammar Check Icon to an "X". This serves to notify the user that there is an error in spelling or grammar.
