If you can’t stand homophonic errors, then you shouldn’t be reading Yahoo! Shine. Especially this:
This writer is a loose cannon, who can screw up something as simple as a book title. (Huck Finn is a character; the book is “The Adventures of Huckleberry Finn.”)
I assume that the “cannon” she refers to is Christopher Cannon, the author of “The Grounds of English Literature.” But that makes no sense. This loose cannon doesn’t know the difference between a large weapon that fires large balls and a group of literary works (that would be a canon).
