This document discusses the difference between common nouns and proper nouns. Common nouns refer to general people, places, or things and do not require capitalization unless starting a sentence. Proper nouns specifically name a person, place, or thing and are always capitalized, such as names, specific locations, or titles. While every proper noun has a common noun equivalent, not every common noun can be converted into a proper noun.

kind of dust, so it's just common.
