1147. In this bonus segment that originally ran in October, we look at the fascinating history of the "new letters" of the alphabet — V, W, X, Y, and Z. Danny Bate explains why T was the original end of the alphabet and how letters were added by the Greeks and Romans. We also look at the origin of the letter Y, which was originally a vowel, and the two historical reasons we call the final letter “zee” or “zed.”

1142. This week, we look at the history of the phrase "pride and prejudice," which was used frequently before Jane Austen’s 1813 novel. Then, we look at whether Parson Brown from “Winter Wonderland” was a real person, and why his name is sometimes replaced with a “circus clown.”

1137. In this bonus conversation with Rob Drummond from back in June, he and I get into the fascinating concept of "languaging" — the idea that speaking is an active process we use to constantly shape and project our identities. Rob explains how our "speaking identities" are incredibly fluid, changing based on context, audience, and even the language we're using.

1136. This week, we go full Thanksgiving, talking about the origin of butter knives, forks, and more. You'll love all the tidbits you can share with your family or friends during dinner.

1135. This week, we talk with Peter Sokolowski, editor at large at Merriam-Webster, about the new print 12th Collegiate Dictionary.
