106: Is a hotdog a sandwich? The problem with definitions

We asked you if a burrito was a sandwich, and you said 'no'. We asked you if ravioli was a sandwich and you said 'heck no'. We asked you if an ice cream sandwich was a sandwich and things...started to get a little murky. This isn't just a sandwich problem: you can also have similar arguments about what counts as a cup, a bird, a fish, furniture, art, and more! So wait...does any word mean anything anymore? Have we just broken language?? It's okay, linguistics has a solution! In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about why deciding what's in and what's out of the definition of a word is so dang tricky, why people love to argue about it, and how prototype theory solves all the "is X a Y" arguments once and for all. Note that this episode originally aired as Bonus 9: Is X a sandwich? Solving the word-meaning argument once and for all. We’ve added an updated announcements section to the top and a few new things about prototypes and meaning to the end.

We talk about the Vulcan salute from Star Trek, the Wakanda Forever salute from Black Panther, and the three-finger Hunger Games salute, and how all three have crossed over with additional symbolism into the real world. We also talk about gestures that have crossed over in the other direction, from the real-world origins of the Vulcan salute in a Jewish blessing, the two-finger blessing in the Foundation tv series from classical Latin and Greek oratory via Christian traditions, as well as religious gesture in the Penric and Desdemona series, smiles and shrugs in A Memory Called Empire, and more.
