Name

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'', formed from variants to ''shui'', meaning "water".
