About Punctuation

Punctuation marks are conventions of print. The rules we use were not established until the second half of the 17th century. (That's why you see Shakespeare break so many of them.) We need punctuation marks when we write, though, because like other conventions (thank you notes, for instance), punctuation helps readers understand writers' messages. Besides, learning these conventions establishes your credibility as a writer. When you use them correctly, you demonstrate your ability to participate in a community of highly-literate language users.
You may be surprised to learn that conventions of punctuation differ from language to language. There are even differences between American and British usage:
In America we put the period inside quotation marks:
" . . . especially at the end."
The British put the period outside the quotation marks:
" . . . especially at the end".
The material presented on these pages reflects standard American English conventions.
You may also be surprised to learn that there is some disagreement about which conventions are correct. You'll encounter variations depending on which handbook you consult. When we've encountered disagreement, we've used the handbook that the Auburn University English Department requires in its core courses: The Holt Handbook.
