All the grammar, punctuation, and usage rules and examples on the website plus dozens of quizzes with answers.
Note: Some English usage rules vary among authorities. For example, the Associated Press (AP) Stylebook is a guide specific for news media and journalists while The Chicago Manual of Style (CMS) is used by many book publishers and writers. The Blue Book of Grammar and Punctuation leans towards usage rules in CMS along with other authoritative texts and does not attempt to conform to the AP Stylebook, which differs significantly in some aspects.
