Vietnam is located in the Han culture region, so the Vietnamese language also has many similarities with other languages in the Austroasiatic language family. Vietnamese is a standard tonal language with 6 tones: horizontal, sharp, profound, question, fall, and heavy. Vietnamese vocabulary has 2 main parts: pure Vietnamese words and borrowed words. There are also mixed-race words that are the result of a combination of pure Vietnamese and foreign elements.
