Hi Sara, You get a red line under your word when you misspell it. When you correct the spelling, the red line goes away. You say you go back and spell your word correctly, and the line is still there. Well, you probably go back, change the spelling of the word, but still spell it wrong. That is why the line is still there. When you finally do spell the word correctly, the red line will disappear. Grammar is the way you use your language. For instance, if you say, I ain't got no money, you are using incorrect grammar. The proper way to say this, or the proper grammar is I don't have any money. Now I want you to go to the library and get some books on spelling and grammar. Study them very carefully, and soon you will be spelling all of your words correctly, and you won't be seeing any more red lines. Happy learning!
