Predicative Adjectives

The use of predicative adjectives in academic writing

Subject and Object Predicative Adjectives

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

Subject predicatives complement a copular verb and give information about the subject.

  • Sneezes are powerful for a reason! (Sorg 2021)

    The noun "sneezes" is the subject, "are" is a copular verb, and "powerful" is a predicative adjective. The adjective is complemented with a prepositional phrase, "for a reason".
  • Some languages seem harder than others. (Sorace 2023)

    The noun "Some languages" is the subject, "seem" is a copular verb, and "harder" is a predicative adjective . The adjective is complemented with a comparative phrase, "than others".
  • After age 30, people start to become a little bit shorter. (Bogin 2020)

    The noun "people" is the subject, "become" is a copular verb, and "shorter" is a predicative adjective . The adjective is modified by the adverb phrase, "a little bit".

Object Predicatives

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

  • It can make them worse.(GrovĂ© 2019)

    The pronoun "them" is a the object of the verb, "make", and "worse" is an object predicative.
  • This is another adaptation to keep them warm. (Younger 2019)

    The pronoun "them" is a the object of the verb, "make", and "warm" is an object predicative.
  • But perhaps having a partner with a compatible personality makes all these things slightly easier to manage. (McCully 2023)

    The noun phrase "all these things" is a the object of the verb, "makes", and "easier" is an object predicative postmodified by a to-clause, "to manage".
  • Things such as the structure of a compound and its stability can make it more complex and difficult to make. (Addicoat 2023)

    The pronoun "it" is a the object of the verb, "make", and "more complex and difficult" is an object predicative (comparative with two adjectives) postmodified by a to-clause, "to make".

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.


Adjectives which are predominantly predicative

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.
