茶

The Chinese character 茶 has two ancient pronunciations: 'cha' (Cantonese/Mandarin) and 'te' (Min/Hokkien). Which word a language uses for tea reveals its historical trade route with China.

Countries that got tea overland — via the Silk Road or from Canton — say 'cha': Hindi chai, Japanese cha, Turkish çay, Russian чай, Portuguese chá. Countries that got tea by sea — from Fujian's ports — say 'te': English tea, French thé, Spanish té, Dutch thee.

This single word splits the entire world into two camps, and each camp maps perfectly onto centuries-old trade networks. Your word for tea is a fossil of commerce.

The character 茶 itself evolved from 荼 (tú, a bitter herb). The legendary emperor Shennong supposedly discovered tea in 2737 BCE when leaves blew into his hot water.
