The Learnerer is a villain who irritates WordGirl, because of his tendency to overuse suffixes. For example, his very name is a play on the word learner. He has the ability to see something once, and instantly learn it. And, he would manipulate his suit to get through obstacles. In the episode "The Learner," he steals the Santa Tortuga diamond from Ms. Von Hoosinghaus. While fighting WordGirl, he proved to be hard to handle, because he would study her moves, and learn from his mistakes. However, he didn't consider Huggy Face a threat, and he was defeated and arrested. He also briefly appeared in the WordGirl television movie "The Rise of Miss Power." He was voiced by "Weird Al" Yankovic.
