Double possessives. Words that do double duty. The monkeys aren't working.

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.

1105. This week, we look at how the pronouns you use can reveal your psychological state — for example, how using "I" versus "we" can signal how you are coping with a breakup or a tragic event. Then, we look at where our alphabet started, from ancient Egyptian hieroglyphs to the Phoenicians and Romans.

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.
