When To Use Commas Between Adjectives

Describing something vividly often involves using multiple adjectives, but knowing when to separate them with commas can be tricky. Mastering comma usage with adjectives is crucial for clear and effective writing.

Understanding Adjectives and Their Order

Adjectives are words that modify nouns, providing more detail about their qualities or characteristics. In English, adjectives typically appear before the noun they modify. For instance, in the phrase "a beautiful red rose," "beautiful" and "red" are adjectives describing the noun "rose."

While there's a general order for adjectives in English, knowing this order isn't as critical as understanding when to use commas between them. The order is generally:

1. Quantity: one, two, several
2. Opinion: beautiful, ugly, interesting
3. Size: large, small, tiny
4. Age: old, new, ancient
5. Shape: round, square, triangular
6. Color: red, blue, green
7. Origin: French, American, Japanese
8. Material: wooden, metal, plastic
9. Purpose: writing (as in writing desk), sleeping (as in sleeping bag)

For example, you might say "a beautiful large old round red French wooden table." However, it's rare to use so many adjectives together! The more important thing to remember is how to use commas when you do use multiple adjectives.

The Two Types of Adjectives: Coordinate vs. Cumulative

The key to understanding comma usage between adjectives lies in distinguishing between coordinate and cumulative adjectives.

Coordinate Adjectives

Coordinate adjectives independently modify the noun and can be rearranged without changing the meaning of the sentence. They can also be joined by the word "and."

• How to Identify Coordinate Adjectives:

  • Rearrangeable: The order of the adjectives can be switched without affecting the sentence's meaning.
  • Replaceable with "and": You can insert "and" between the adjectives without making the sentence sound awkward.

• Examples:

  • "She wore a comfortable, warm sweater." (You could also say "a warm, comfortable sweater" or "a comfortable and warm sweater.")
  • "He had a kind, gentle smile." (You could also say "a gentle, kind smile" or "a kind and gentle smile.")
  • "The movie was long, boring, and predictable."

• Comma Rule: Separate coordinate adjectives with a comma. If there are three or more coordinate adjectives, use the Oxford comma (the comma before the "and").

Cumulative Adjectives

Cumulative adjectives, on the other hand, build upon each other to modify the noun. They cannot be rearranged, and you cannot insert "and" between them without making the sentence sound unnatural. The first adjective modifies the combination of the following adjectives and the noun.

• How to Identify Cumulative Adjectives:

  • Not Rearrangeable: The order of the adjectives cannot be switched without affecting the sentence's meaning or sounding awkward.
  • Not Replaceable with "and": Inserting "and" between the adjectives sounds unnatural.

• Examples:

  • "She lived in a small brick house." (You wouldn't say "a brick small house" or "a small and brick house.") "Small" modifies the brick house.
  • "He drove a fast sports car." (You wouldn't say "a sports fast car" or "a fast and sports car.") "Fast" modifies the sports car.
  • "They adopted a cute little puppy." (You wouldn't say "a little cute puppy" or "a cute and little puppy.") "Cute" modifies the little puppy.

• Comma Rule: Do not separate cumulative adjectives with a comma.

Applying the Rules: Examples and Explanations

Let's look at more examples to solidify your understanding of when to use commas between adjectives.

Coordinate Adjectives (Commas Needed):

• "The tall, handsome stranger walked into the saloon." ("Handsome, tall" also works, and so does "tall and handsome.")
• "The restaurant served delicious, authentic Italian food." ("Authentic, delicious" also works, and so does "delicious and authentic.")
• "The presentation was clear, concise, and engaging." (All three adjectives independently describe the presentation. "Clear and concise and engaging" works grammatically, hence needing commas.)

Cumulative Adjectives (No Commas Needed):

• "She bought a new red dress." ("New" modifies the red dress. You wouldn't say "a red new dress" or "a new and red dress.")
• "He lived in a charming Victorian house." ("Charming" modifies the Victorian house. You wouldn't say "a Victorian charming house" or "a charming and Victorian house.")
• "They adopted a small black cat." ("Small" modifies the black cat. You wouldn't say "a black small cat" or "a small and black cat.")
• "They have a big old dog." ("Big" modifies the old dog. You wouldn't say "old big dog" or "big and old dog.")

Tricky Cases and Exceptions

Sometimes, determining whether adjectives are coordinate or cumulative can be challenging. Here are some tricky cases and exceptions to keep in mind:

1. Adjectives of Color and Origin: These are usually cumulative, especially when they appear close to the noun.

   • "Bright blue sky" (No comma)
   • "Italian leather shoes" (No comma)

2. Adjectives Describing Age and Material: These are also typically cumulative.

   • "Old wooden chair" (No comma)
   • "Antique silver locket" (No comma)

3. When an Adjective Acts as Part of a Compound Noun: If an adjective is closely linked to the noun and functions as part of a compound noun, don't use a comma.

   • "High school student" (Here, "high" describes the type of school, not the student directly.)
   • "Real estate agent" (Similarly, "real" describes the type of estate.)

4. Series of Adjectives with Different Functions: If you have a series of adjectives where some are coordinate and others are cumulative, apply the rules accordingly. This can get complex, so careful consideration is needed.

   • "She wore a beautiful, flowing white silk gown." ("Beautiful" is coordinate with the rest, but "white silk" are cumulative.)
   • "He drove a fast, powerful German sports car." ("Fast" and "powerful" are coordinate, but "German sports" are cumulative.)

Common Mistakes to Avoid

• Overusing Commas: Resist the urge to put a comma between every adjective. Remember to apply the coordinate vs. cumulative test.
• Forgetting the Oxford Comma: When you have a series of three or more coordinate adjectives, always use the Oxford comma (the comma before the "and"). This helps avoid ambiguity.
• Relying Solely on Intuition: While your intuition can be helpful, it's essential to understand the rules and apply them consciously.
• Ignoring the Sound of the Sentence: Read the sentence aloud. If it sounds natural to pause between the adjectives or insert "and," they are likely coordinate and need a comma.

Practical Tips for Mastering Comma Usage with Adjectives

1. Practice Regularly: The more you practice identifying coordinate and cumulative adjectives, the easier it will become.
2. Read Widely: Pay attention to how professional writers use commas with adjectives in books, articles, and other publications.
3. Use Online Resources: Many websites and grammar guides offer exercises and explanations to help you improve your comma usage.
4. Seek Feedback: Ask a friend, colleague, or teacher to review your writing and provide feedback on your comma usage.
5. Consult a Style Guide: If you're writing professionally, refer to a style guide such as the Chicago Manual of Style or the AP Stylebook for specific rules and guidelines.
