My ever-lovin' sister, who can't let a grammatical error pass her by, has cited me for another one. Recently, in each of my Toxicology posts on rodenticides, I have asked you to give me the toxic princiPAL of each poison when I meant the toxic princiPLE.
Guilty, Your Honor.
The former means the first or most important, as in "principal dancer of the ballet" or a person who has controlling authority, as in "my high school principal." PrinciPLE refers to the "primary source" or "the underlying law or fact."
Sheesh. Not only do I have to keep the Science Chimps happy, now I have the Grammar Gorilla on my back. If there are any Math Monkeys out there, I tell you now, I promise there will be math errors.
