What kind of adjectives could one create?
I mean, there are a lot of adjectives that are compound, but if you looked them up in a dictionary, you wouldn’t see them. You understand their meaning as they are formed.
- Your red-colored eyes are so beautiful.
- I saw a man-eating shark.
- I live in an English-speaking country.
- We live in a densely populated city.
You would not find “red-colored”, which is considered to be a compound adjective, in dictionaries. But it is easy to understand that it means that the color of your eyes, which are red, is so beautiful.
On the other hand, there are a lot of compound adjectives that do exist in dictionaries.
well-known; short-lived; fishing-dependent; modern-day
- She is a world-famous singer.
- This is a smoke-free restaurant.
Why do these exist but the ones above not?
I have two questions. The first is: Could anyone combine words to make the term they want without the term or compound words already being in a dictionary? Are there any rules to follow related to this matter?
The second is: when should one hyphenate the adjectives?
