Proper nouns

Capitalize proper nouns

  • A proper noun is the name of a particular person, place, or object that is spelled with a capital letter
  • In contrast, a common noun is a noun that is the name of a group of similar things, such as "pump" or "valve", and not of a single person, place, or thing and is not capitalized
  • In the context of industrial applications, proper nouns might be company and product names, tools or existing technical and legal terms
  • Avoid making up your own proper nouns, e.g. ball valve instead of Ball Valve
