Criminal Sentence 10: Pour vs. Pore

This is an especially egregious example because it comes from the acknowledgments in a grammar book. The author is thanking his copy editor:

"She poured over each page of the manuscript with youthful laughter, unwavering encouragement, and sage advice."

After I got over the shock of reading this, I had to laugh youthfully.

"To pour over" is to dispense liquid on top of something or someone. "To pore over" is to study something carefully.

Please pore over your writing and proofread, or I'll have to come pour something over you!
