Frindle by Andrew Clements

Nick Allen is the king at asking the best time-wasting questions to get the entire class out of homework. That is until he meets Miss Granger, or the “Lone Granger” as the kids call her. He launches his first (and last) ever time-waster bomb in her class – “Why does the word dog means the thing that goes woof?” Instead of giving him a straight answer, Miss Granger sets Nick to discover why for himself. He does and that gives him an awesome idea for a new experiment. With a few of his friends on board, he launches a new word into circulation. “Frindle” takes off and is soon being used by his entire school much to Miss Granger’s disapproval. “The dictionary and it’s contents should not be messed with.”
