"Heroine"- with an "E" at the end, is the word that describes the woman who's going to save the day- a female hero. "Heroin" without the "E" is the word Vampire Edward uses as he speaks to love interest Bella during a scene in the 2008 movie Twilight.

"Grammar Girl" Mignon Fogarty alerts us to problem words like "heroin" in her new book "101 Misused words You'll Never Confuse Again." Next on "All Sides," we'll have a grammar and vocabulary lesson, with the Grammar Girl. That's this hour on All Sides with Ann Fisher, 89-seven, NPR News.
