X-Word Grammar provides an editing technique for students that is more reliable than trying to identify sentences as complete thoughts. A sentence is redefined as "a group of words that can be turned into a yes-no question with no words left over; starts with a capital letter, and ends with a terminal punctuation mark." Twenty auxiliary verbs play a key role by moving around the subject of a sentence to identify the correct structure of a sentence using both visual and oral means. Stressing editing skills, teachers can use X-Word Grammar as a means to simplify sentence punctuation, address verb endings, carry out other tasks in editing and evaluating writing.
