1095. Is “sick” really “good”? This week, we explore how words flip their meanings and why language changes over time. Then, we look at the 1950s idea of "U and Non-U English" and what it tells us about social climbing.

The "sick" segment was written by Natalie Schilling, a professor emerita of linguistics at Georgetown University in Washington, DC, and who runs a forensic linguistics consulting firm. You can find her on LinkedIn.

The "posh" segment was by Karen Lunde, a former Quick & Dirty Tips editor and digital pioneer who's been spinning words into gold since before cat videos ruled the internet. She created one of the first online writing workshops, and she's published thousands of articles on the art of writing. These days, she leads personal narrative writing retreats and helps writers find their voice. Visit her at ChanterelleStoryStudio.com.
