J.K. Rowling uses lots of charactonyms throughout the Harry Potter series. Merriam Webster defines charactonym as “a name for a fictional character that suggests a distinctive trait of the character.” In Harry Potter and the Prisoner of Azkaban, a new Defense Against the Dark Arts teacher is hired and his name is Remus Lupin. Lupin is very similar to the word lupine, an adjective which means of or relating to a wolf. Lupine comes from the Latin word lupus meaning wolf. Lupin’s name betrays what he actually is, a werewolf! I like trying to decipher the charactonyms that J.K. Rowling uses in her books, because it makes the books more interesting and exciting.
