I can recommend the book, “Eats, Shoots and Leaves” by Lynne Truss, “The Zero-Tolerance Approach to Punctuation.” She has written a serious, yet light-hearted review of the simple rules of pronunciation, without being a scold.
She also provides several pages of large stick-on commas, question marks and apostrophes for correcting signs in public places.
Haifagirl, I went to graduate school in an engineering discipline, and was also astonished at the number of fellow students who couldn’t write clearly. How do you make your thoughts known to others?
The title of the book comes from a joke: A panda walks into a cafe, orders a sandwich, eats it, then draws a gun fires two shots,
“Why?” asks the waiter. The panda produces a poorly-punctuated wildlife manual and gives it to the waiter.
“I’m a panda,” he says at the door, “Look it up.”
The waiter turns to the entry, and there’s an explanation.
“Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves.”
