The Difference Between Complements and Predicatives in English: Understanding the Distinction

English grammar encompasses various elements that contribute to the structure and meaning of sentences. Two crucial components are complements and predicatives. While they both serve to provide additional information about the subject or object in a sentence, they differ in their roles and syntactic positions. Understanding the disparity between complements and predicatives is essential for constructing coherent and accurate sentences.

Defining Complements

Complements are elements in a sentence that complete the meaning of a verb, adjective, or preposition. They are necessary for the sentence to convey a complete thought. Complements can be divided into different categories based on their syntactic functions. For instance, objects, whether direct or indirect, are considered complements because they complete the action of the verb. Similarly, complements can also function as modifiers, providing additional information about the subject or object.

Understanding Predicatives

Predicatives, on the other hand, are elements that provide information about the subject or object and are typically linked to them by a copular verb such as "be," "become," "seem," etc. Unlike complements, which are obligatory to complete the meaning of the verb, predicatives offer additional description or identification of the subject or object. They can take the form of adjectives or nouns and are essential for conveying the full sense of the sentence.

Distinguishing Characteristics

One of the key distinctions between complements and predicatives lies in their necessity within a sentence. Complements are indispensable for the sentence's coherence and grammaticality, whereas predicatives provide supplementary information but are not obligatory. For example, in the sentence "She painted the wall blue," "blue" is a complement because it completes the action of painting. However, in the sentence "She seemed happy," "happy" is a predicative providing additional information about the subject "she."

Syntactic Positions

Complements and predicatives also differ in their syntactic positions within a sentence. Complements typically follow the verb or preposition they complement, whereas predicatives appear after the subject and are linked to it by a copular verb. This distinction is crucial for identifying whether a particular element in a sentence functions as a complement or a predicative.

Examples and Analysis

Consider the following examples to further elucidate the disparity between complements and predicatives:

Complement: "They elected him president."

Predicative: "He is happy."

In the first example, "president" functions as a complement because it completes the action of "elected" by specifying what position he was elected to. In the second example, "happy" serves as a predicative, providing additional information about the subject "he."

Conclusion

Understanding the distinction between complements and predicatives is essential for mastering English grammar and sentence construction. While complements complete the meaning of a verb, adjective, or preposition, predicatives provide additional description or identification of the subject or object. Recognizing their roles and syntactic positions enables writers to craft precise and grammatically correct sentences.
