A ‣ Form and meaning 
A compound adjective has two parts. It is usually written with a hyphen, e.g. well-dressed, never-ending, sky-blue. Its meaning is usually clear from the combined words. The second part of the adjective is often a present participle (ending in -ing) or past participle (ending in -ed, except for irregular verbs).
Language help
Some compound adjectives use a hyphen before a noun but not after a verb (e.g. a well-dressed man but He is always well dressed).
B ‣ Personal appearance 
A number of compound adjectives describe personal appearance. Here is a rather far-fetched description of a person starting from the head down. [hard to believe]
Tom was a curly-haired, suntanned, blue-eyed, rosy-cheeked, thin-lipped, broad-shouldered, left-handed, long-legged young man, wearing an open-necked shirt, brand-new, tight-fitting jeans and open-toed sandals.
C ‣ Personality and character 
Other compound adjectives describe a person's character.
Melissa was absent-minded [forgetful], easy-going [relaxed], good-tempered [cheerful], warm-hearted [kind] and quick-witted [quick-thinking/sharp], if perhaps a little big-headed [proud of herself], two-faced [not sincere], self-centred [always thinking about herself instead of others] and stuck-up [thinks she's better than other people (colloquial)] at times.
D ‣ Prepositions and particles 
Another special group of compound adjectives has a preposition or particle in its second part.
The workers’ declaration of an all-out strike forced management to improve conditions. [total]
Once there were fields here but now it's a totally built-up area.
That student’s parents are very well-off [rich] but they don't give him much money and he is always complaining of being hard-up. [poor]
