Rules For Capitalization Questions Medium
In general, the word 'river' should not be capitalized unless it is part of a proper noun or used as the first word in a sentence. Proper nouns, such as the names of specific rivers like the Mississippi River or the Nile River, should always be capitalized. However, when referring to rivers in a general sense, such as "the river flows peacefully," the word 'river' should be written in lowercase.
