Principal vs. Principle: Who's Your Pal?

Rebecca from St. Louis says:

"I am amazed that nobody has fixed this headline, which was posted by our local TV station back in December."

Zoinks! I see what you mean.

Where did KMOV.com go wrong? It confused the homophones "principal" and "principle."

Definitions:

• principal (n.) - the chief administrator of a school
• principle (n.) - a basic truth, law, or belief

Nifty Mnemonic:

• Principal ends in "pal" and a principal can be a pal.
