Is persistence a proper or common noun?

Answer 1

The word persistence is a common noun, a word for the persistence of any one or any thing.

A proper noun is the name of a person, a place, a thing, or a title; for example:

• Persistence Cove, Plymouth MA; Persistence Drive, Heritage Creek KY; or Persistence Avenue, Pine CO
• "Persistence of the Color Line" By Randall Kennedy
• "The Persistence of Crows" (novel) by Grant Maierhofer
• "The Persistence of Memory" (painting) by Salvador Dali

Answer 2

Persistence is a common noun. Proper nouns are the unique names of people, places, or things. Common nouns are the words for general things. If a common noun is part of a name, it becomes a proper noun. Pronouns always replace proper and common nouns.

Answer 3

It can be either. This is due to the fact that it is mostly used as a common noun, but also it is used as a proper noun, to the fact if it is used in a name or thing or place. ;)
