Question

what is common noun and proper noun in this sentence the Nile is is a famous river​

Answer 1

Answer:

Nile is proper noun here and River is a common noun

Answer 2

Answer:

River is not a proper noun unless it's part of the name of the river. For example, in the name Jack's River, river is part of the name, therefore it is 'proper'. If you are speaking generically of a river, of course it wouldn't be a proper noun. For example, the river is wide.
