There are several things that you can do on Grammaropolis: learn about the different characters on the site [the parts of speech], watch videos, read a book, listen to songs, play games.
You will “meet” Adverb, Linking Verb, Pronoun, Adjective, Preposition, Slang, Noun, Conjunction, Interjection, and Action Verb. Each character is personified with personalities inspired by their grammatical roles in a sentence. The characters interact with each other the same way that parts of speech interact in a sentence.
