"I'm a linguist." Tongue Twister replied, "I study languages. How they are related to each other. How they change over time. How one language splits into many. How two languages can fuse into a new one.
I'm currently studying the Qetzalcoatlan languages. There are at least six major dialects in use in the Tenochtitlan Basin. The nomadic tribes are small and isolated, which tends to allow languages to diverge. But they move around and encounter each other quite often, which tends to allow different languages to fuse into a new one. So I'm trying to piece together what the original language was, before it gets too mixed.
There is a saying amongst linguists : 'when a language dies, a world ends. When a language is deciphered, a new world opens up.' Look at how much more we learned about the ancient cultures of Pharaoh's Veil once Champonyon deciphered their hieroglyphics !
As for the Prench travel guide, I need it to get my dad out of a tight spot.
He's kind of what you'd call a curio merchant. 'Strange and unusual things from strange and unusual places - for reasonable prices !'" she stated with a melodramatic florish, "In one of his ads, he said 'he had (or could get) anything you could ever want.' Most ponies would realize that was just marketing hype, and not take it seriously; unfortunately, a litigious busybody decided to sue him for false advertising ! She wants to take his shop unless dad can get her a first edition 'Hitchhiker's Guide to Equestria' written in Prench !
She says it her original culture, but she's about as Prench as Prince Rutherford of Yakyakistan !"
She paused for a bit to catch her breath, before realizing something. "Oh, sorry sir ! I've been prattling on, and we don't even know each other's names !
I'm Tongue Twister. I work for the Manehatten Museum of Natural History, mostly."
