For years, I've felt that gaming has helped my vocabulary. Final Fantasy, in particular, taught me so many religious and mythological references as I grew up. The Civilization series introduced me to a lot of history. But yesterday, I had a moment when gaming and vocabulary really came to my mind. I was watching the Great British Baking Show, and one of the contestants was designing a pie to depict the Kohinoor, a diamond that -- according to Wikipedia -- is part of the British crown jewels and was ceded to Queen Victoria following a war in the 19th century.
I had only ever heard of the Koh-i-Noor (intentional alternate spelling) once before this: as a treasure demon in Persona 5. It was great to watch the show and think, "oh, I learned about that from a game!"
How has gaming improved your vocabulary?
EDIT: Per my post later in the thread, I fixed the title.
