What are Compound Adjectives?
A compound adjective is an adjective that is made up of two or more words working together to describe a noun. These words are usually connected with a hyphen (-) to form a single idea. Compound adjectives help make descriptions more specific, clear, and detailed.

The Importance of the Hyphen
The hyphen plays a very important role in compound adjectives. It makes sure that the two or more words are understood as one single idea. Without the hyphen, the meaning of the sentence can be confusing.

When to Use a Hyphen in Compound Adjectives:
1. Before a Noun:
Use a hyphen when the compound adjective comes before the noun it describes. This ensures the words are seen as a single idea.
Example:
- A well-known actor (Correct)
- A well known actor (Incorrect)
2. With Numbers and Measurements:
Use a hyphen when numbers or measurements form part of a compound adjective before a noun.
Example:
- A five-year-old boy
- A 10-mile journey
3. Avoid Confusion:
Use a hyphen to avoid confusion or misreading when combining words might otherwise be unclear.
Example:
- A small-business owner (The owner of a small business)
- A small business owner (Could be misunderstood as a business owner who is small in size)
4. With Well- and Other Adverbs Ending in -ly (for adjectives):
Use a hyphen after words like “well-” and other adjectives that end in -ly, but only before the noun.
Example:
- A well-organized event
- A carefully-planned trip
5. For Certain Prefixes:
Use a hyphen with some prefixes (like ex-, self-, all-) and when the base word is capitalized.
Examples:
- Ex-president
- Self-employed
- All-inclusive vacation
- Non-English speaker
When to Avoid a Hyphen in Compound Adjectives:
1. After the Noun:
Don’t use a hyphen when the compound adjective comes after the noun in the sentence.
Example:
- The boy is five years old. (No hyphen after the noun)
2. With Very or Adverbs Ending in -ly (for verbs):
Do not use a hyphen with adverbs ending in -ly or words like “very.”
Example:
- A very well organized event (No hyphen with “very” or “well”)
- A beautifully decorated room (No hyphen with -ly adverbs)
3. With Common Compound Nouns:
Some compound adjectives or nouns have become so common that the hyphen is no longer needed.
Example:
- High school (No hyphen needed)
- Living room (No hyphen needed)
4. When the meaning is clear without it:
If the meaning is already clear, the hyphen can be avoided in certain cases.
Example:
- A chocolate chip cookie (No hyphen needed; the meaning is clear.)
