A Myriad of Tongues explores profound global linguistic diversity, challenging assumptions about universal human cognition. The book reveals how varied languages—especially those from non-WEIRD populations—shape fundamental concepts like time, space, and kinship. Discoveries show that grammatical features, vocabulary (e.g., odor terms, snow words), and even sound systems are influenced by culture and environment. This research underscores that language structure profoundly reflects and potentially affects how people think.
