When does adjective order matter?

When adjectives of different categories are used to describe the same noun or pronoun, these are cumulative adjectives, and they must be listed according to the following order:

  1. Opinion
  2. Size
  3. Physical quality
  4. Age or shape
  5. Color
  6. Origin or religion
  7. Material
  8. Type
  9. Purpose

So, if a sentence uses the adjectives “silk” (material), “19th-century” (age), “delicate” (physical quality), and “ruby-red” (color) to describe a kimono (the noun), the adjectives should occur in this order: “a delicate 19th-century ruby-red silk kimono.”
