Name

The Russian name Amur comes from the Tungusic term for “river”. Tungusic peoples are an ethno-linguistic group formed by the speakers of Tungusic languages (or Manchu–Tungus languages). They are native to Siberia and Northeast Asia.

Historically, it was common to refer to a river simply as "water". There are similar words for "water" or "river" in a number of Asiatic languages: e.g. 물 mul ("water") in Korean, muren or mörön ("river") in Mongolian, and 水 midu > mizu ("water") in Japanese. The name "Amur" may have evolved from a root word for water, coupled with a size modifier for "Big Water".

Its ancient Chinese names were Yushui, Wanshui and Heishui, with the latter name, meaning "black water", being the basis of the modern Chinese name Heilongjiang or " Black Dragon River", while the Manchurian name Sahaliyan Ula, the Mongolian names "Amar mörön" (Cyrillic: Амар мөрөн) originates from the name "Amar" meaning to rest and Khar mörön (Cyrillic: Хар мөрөн) mean Black River.
