In Through the Language Glass , linguist Guy Deutscher explores how the language we speak acts as a "lens" that filters our perception of the world.

: Languages develop color terms in a predictable sequence: Black/White, then Red, then Yellow/Green, and finally Blue.

: They would say "there is an ant on your southwest leg".

Deutscher begins with the "wine-dark sea" of Homer’s Odyssey , noting that ancient Greek lacked a word for "blue".

: While everyone sees the same physical light, having a specific word (like the Russian goluboy for light blue) helps speakers distinguish shades faster than those who don't. 🧭 The Internal Compass

Most languages use "egocentric" directions (left, right, front). However, speakers of Guugu Yimithirr in Australia use "absolute" cardinal directions.

: This linguistic requirement forces them to maintain a perfect mental map of north, south, east, and west at all times, even in unfamiliar places or dreams.
