How pronouns reveal our psychology. How'd we get our alphabet? Tabagogox.

1107. This week, we look at double possessives, such as "a friend of Mignon's" and whether they are grammatically correct. Then, we look at words that do double duty, from the nautical origins of "scuttlebutt" to "beetle" — which can be both an insect and a tool.

1106. We talk with Fiona McPherson, a senior editor at the Oxford English Dictionary, about the playful words that get added to the OED. We look at the dictionary's ongoing work to expand its coverage of World Englishes, and Fiona shares some of her favorite recent additions, including "waka jumper" from New Zealand politics and "Rolex," a term for a Ugandan street food.

1104. This week with Martha Barnette, co-host of "A Way with Words" and author of "Friends with Words: Adventures in Languageland," we look at the concept of a "spark word" — the word that ignites a love of language. We also look at fascinating etymologies from ancient Greek, including the surprising connections between "Nike" and "fennel," and the origins of "panic" and "Ritalin."

1103. Why do we talk about "heat waves" but "cold snaps"? This week, we look at the history behind these common weather phrases and other quirky idioms like "raining cats and dogs" and "under the weather." Then, we look at what kind of reading is best for improving your language skills, including research on the benefits of fiction versus nonfiction.

1102. This week, Anne Greene joins us to talk about the importance of writing in plain English, especially in scientific fields. We look at why short words are easier for our eyes to read and how a well-structured story with characters and action verbs can improve understanding. We also discuss how the historical origins of English words influence our writing today.
