Proper nouns

A proper noun is the name of a particular person, place, or object that is spelled with a capital letter
Examples of proper nouns in English are Jennie, Edinburgh, and Digital Enterprise Labs
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
