Understanding Predicative Complements and Objects in English Grammar
Grammar fundamentals include distinguishing between predicative complements (PredComp) and objects in sentence structure. While both can take the form of noun phrases, predicative complements have unique characteristics that set them apart from objects.
A key distinction lies in the ability of predicative complements to take the form of adjective phrases, which is not possible with objects. For example, in the sentence "He became anxious," the adjective phrase "anxious" functions as a predicative complement. However, we cannot say "He hired anxious" because objects cannot be adjective phrases.
Another important difference involves passive voice constructions. While objects can typically become subjects in passive sentences, predicative complements cannot. Consider the sentence "Ed became a friend of mine" - it cannot be transformed into "A friend of mine was become by Ed" as this would be ungrammatical.
Definition: A predicative complement is a word or phrase that follows a linking verb and provides additional information about the subject or object of the sentence.
Example: In "Ted seems highly untrustworthy," the predicative complement "highly untrustworthy" describes the subject "Ted."
