Adjectives qualify nouns or people.
A new big wooden bed (= the bed is a noun. New, big and wooden are adjectives.)
A beautiful slim dark-haired American girl(=the girl is a people. Beuatiful, slim and dark-haired and American are adjectives.)
Attributive adjectives PRECEDE the noun or people.
clever girl(=Adjective before people.)
coloured dress(=Adjective before noun.)
big duck(=Adjective before noun.)
Predicative adjectives FOLLOW the noun or people.
The shoes look expensive (='The shoes' are the subject, 'look' is the linking verb and 'expensive' is a predicative adjective. Follow the noun.)
But if we say:
The expensive shoes (='expensive' is become to attributive adjective. There isn't linking verb. Precede the noun.)
Other example;
The lorry is broken-down (='The lorry' is the subject, 'is' is the linking verb and 'broken-down' is a predicative adjective. Follow the noun.)
But if we say:
The broken-down lorry (='broken-down' is become to attributive adjective. Precede the noun.)
Everything depends of what you want to say.
