"If you've ever shot the breeze, had a heart-to-heart, or bent somebody's ear — in fact, if you've ever talked at all — odds are you've used an idiom. These sometimes bizarre phrases are a staple of conversation, and more than 10,000 of them are collected in the latest edition of The American Heritage Dictionary of Idioms, which came out this week."

"The new volume contains hundreds of new entries. Author Christine Ammer tells NPR's Renee Montagne that idioms are added to the book based on how commonly they're used. 'I usually go by the frequency with which I hear them used and where I see them used in print,' she says. 'There are some that simply jump out at you because they're used so often, even though they may be of very early provenance.'"
