Unlike attributive adjectives, predicative adjectives do NOT precede the nouns they modify. There are two roles for predicative adjectives: subject predicatives and object predicatives.
Subject predicatives complement a copular verb See the glossary definition and give information about the subject.

Object predicatives follow a direct object and describe or classify it.

As you can see from the last two examples, predicative adjectives often have complements of their own such as to-clauses, prepositional phrases, that clauses or than comparative phrases or clauses.
Almost all adjectives can be used either attributively or predicatively but many adjectives with the prefix a- occur predominantly in the predicative position: alike, alive, alone. Adjectives which take complementation also occur predominantly in the predicative position: able, afraid, answerable, anxious, asleep, averse, aware, clear, conscious, essential, difficult, important, impossible, likely, loath, necessary, possible, ready, responsible, subject, sure, unlikely, worse.
