Compound adjectives
A compound adjective is an adjective that contains two or more words.
In general we put a hyphen between two or more words (before a noun) when we want them to act as a single idea (adjective) that describes something.
I live in an English-speaking country.
English-speaking is an adjective (used to describe the country). We use a hyphen to connect the word English with speaking to show that it is one adjective (or one idea).
This adjective with two words joined by the hyphen is called a compound adjective.
Some more examples of compound adjectives are:
Our office is in a twenty-storey building.
I have just finished reading a 300-page book.
He is a well-known writer.
There are many types of Compound Adjectives. Here is a list of the most common types
Periods of Time
When he have compound adjectives using a number + a time period, that word referring to a time period is in singular form and is joined to the number with a hyphen.
I work eight hours every day --> I work an eight-hour day
I'm going on vacation for three weeks --> I have a three-week vacation
There was a delay of 5 seconds --> There was a five-second delay
Notice how we normally write the number as a word, not in numerical form.
Adverbs + Adjectives
Adverbs modify a verb.
She walks slowly.
How does she walk? Slowly. Slowly is an adverb that modifies (or describes) the verb.
Adverbs can also be used to modify an adjective.

She is extremely intelligent. (Extremely is an adverb)
Notice how we do not put a hyphen between an adverb and an adjective (not even before a noun).
It is a very hot day.
She is an extremely intelligent girl.
He is a well known singer.
Adverb + Past Participle
However when we have an Adverb + past participle, we put a hyphen between the two words to make it a compound adjective.
This is a brightly-lit room.
She is a well-known actress.
We live in a densely-populated city.
Noun + Past Participle
When we have a noun + past participle, we put a hyphen between the two words to make it a compound adjective.

Compound Adjectives with Proper Nouns
A proper noun is the name of something or someone (e.g. John, Susan Sanders).
Compound Adjectives made from Proper nouns don't need a hyphen though must have capital letters.
I bought the James Jackson tickets for us.
James Jackson is a compound adjective describing the tickets (What type of tickets? James Jackson tickets). Since the adjective is a Proper noun, we don't need a hyphen between the two names.
How do we know when to put a hyphen?
If you can use the word “and” between the two adjectives or words, then a hyphen isn't necessary.
She has a big blue book.
(Big and Blue are adjectives)
Can we say: She has a big and blue book. (Yes, it is possible)
He is a world famous singer. (Is this correct?)
Can we say: He is a world and famous singer. No, it doesn't sound correct so we need a hyphen to join the words world and famous:
He is a world-famous singer. (Correct)
Also, look at the following:
It's an old coal-mining town
Notice how we didn't put a hyphen between the word old and coal. If we had have done that, we would have been referring to old coal, as in coal that is old. We want to emphasis that the town in old and not the coal.
Here we can say it is old and a coal-mining one.
