The most famous example of the linguistic theory known as the Sapir-Whorf hypothesis is the multiple words Eskimos have for snow.

The Barai have 30 different words for “yam”—one of their staple crops—but only one word for any piece of furniture with a flat surface (i.e., bed, chair, table, bench, desk, counter, and cupboard).
