What is a compound adjective in English?
Compound adjective definition: A compound adjective is a combination of two or more words, usually two, that functions as one word and modifies a noun or pronoun, and works as an adjective.
The words in a compound adjective are joined using one or more hyphens. The number of hyphens used in a compound adjective is the number of words put together minus one.

When to use a hyphen to compound an adjective?
Remembering all the compound adjectives with no hyphen used is almost impossible. The right thing to do is to understand or learn the way to identify if a hyphen is needed to bring the words together.
The trick is simple: if the conjunction ‘and’ can be used between the words, there is no need to use the hyphen.
You are a fat looking guy.
Is the hyphen needed? Exercise what you have just learned. Try using the conjunction ‘and’ in the middle of the words and see if the sentence makes sense.
‘You are a fat and looking guy.’
Does it make sense to you? It actually does not. The present participle ‘looking’ alone does not modify the noun ‘guy’. The words ‘fat’ and ‘looking’ need to be hyphenated. “You are a fat-looking guy.“
It was a short muscular dog.
Use the same technique and see if a hyphen is needed to compound the words ‘short’ and ‘muscular’.
“It was a short and muscular dog.”
The sentence perfectly, still, makes sense after the conjunction ‘and’ is used in between the words ‘short’ and ‘muscular’. It means that we can’t use a hyphen here and bring the words together into a compound word.
Don’t pluralize the last word of a compound adjective!
If the last word of a compound adjective is a number, don’t pluralize it. Use it in the singular form. Using it in the plural is a common mistake both natives and non-natives make.
- What you are looking at is a 50-years-old building. ❌
- What you are looking at is a 50-year-old building. ✅
- This is a three-buildings block. ❌
- This is a three-building block. ✅
- That was a 180-pages report. ❌
- That was a 180-page report. ✅
- He is just coming from a 12-hours shift. ❌
- He is just coming from a 12-hour shift. ✅
Compound adjectives are not always hyphenated
We often use a phrase or a clause as a compound adjective when the entire part modifies a noun in a sentence. These expressions are not always hyphenated. Sometimes, the writer uses quotation marks or italicizes the entire expression to indicate that it is being used as a compound adjective.
She had an ‘I know nothing about it’ look on her face when asked the question about neuroscience.
In this sentence, the entire clause ‘I know nothing about it; works as an adjective. It describes the noun ‘look’. Notice that we have used quotation marks to highlight the compound adjective.
I bought him an ‘out of my budget’ gift the other day.
The compound adjective is a phrase in this example. It modifies the noun ‘gift’ and tells us what kind of a gift the speaker is talking about.
It is actually fun to use these ‘more than a word ‘ adjectives.
In this example, we have chosen to do both: use quotation marks and italicize the compound adjective to highlight it. This is a choice that the writer has.
I love your ‘never give up’ attitude.
In this example, we have chosen to do both: use quotation marks and italicize the compound adjective to highlight it. This is a choice that the writer has.
More examples:
- She had an ‘I know nothing about it’ look on her face when asked the question about neuroscience.
- People who have an ‘I can do anything’ attitude succeed easily in life.
