When you type a word in Microsoft Office program, the spelling checker compares the words in your document against the installed dictionary in Office. If the word is not found in the dictionary, it will be indicated by red wavy lines. You can add words and special capitalization to a custom dictionary to prevent the spelling checker from flagging certain proper names, technical terms, acronyms, or specialized capitalization as mistakes. If you accidentally add a wrong word to the dictionary, you can remove the word from custom dictionary.
Adding words to the dictionary can help you erase red wavy underlines. Before choosing this option, make sure the word is spelled correctly. To do: Right-click on the word, select Add to dictionary.
