Capitalize the letters used to indicate form or shape.

Do NOT capitalize any of the following:

  • A prefix attached to a proper noun: un-American
  • Seasons of the year: fall, spring, winter, summer
  • A common noun shared by (and coming after) two or more proper nouns: Hudson and Atlantic avenues
  • Words used to indicate the direction: north, south, east, west
