In the first half of Andrew Clements's book Frindle, Mrs. Granger actively rebels against the children's use of the made-up word frindle.
Mrs. Granger's first response is to tell Nick his idea to create a new word to call a pen by is a "funny idea," but she doesn't want his idea to create disorder in her classroom. When the students continue to use the word frindle, such as by posing for their fifth-grade class photo by holding up pens and saying frindle, Mrs. Granger hangs up a poster forbidding the use of the word in class and warning that students who use it will be made to stay after class and write "I am writing this punishment with a pen" one hundred times (39). As the battle persists, Mrs. Granger upholds her warning, and on certain days as many as 200 children are held after school.
After Nick's invention of his word is reported in the news, Mrs. Granger halts her attack of the word even though kids have not stopped using it. The narrator reports, "Her poster about the forbidden word had quietly disappeared from the bulletin board, and kids were not staying after school writing sentences anymore" (73). The narrator also reports that each week, Mrs. Granger put the word pen on her spelling test, and each week every fifth grader is marked wrong because "every kid spelled it f-r-i-n-d-l-e" (75).
