In grammar, a complement is a word, phrase, or clause that provides necessary information to complete the meaning of a sentence. It adds depth and specificity to the subject, verb, or object in a sentence. Without a complement, the sentence may feel incomplete or lacking vital information.
Complements are commonly associated with verbs, as they often provide additional details about the action or state expressed by the verb. In this context, they can be classified into three types: object complements, subject complements, and adverbial complements.
Object complements follow a transitive verb and provide more information about the direct object. They answer questions such as “what” or “whom.” For example, in the sentence “I consider him a friend,” the word “friend” is the object complement as it completes the meaning of the verb “consider” and provides more information about the direct object “him.”
Subject complements, on the other hand, follow a linking verb and provide more information about the subject. They can be either predicative adjectives (describing the subject) or predicative nouns (renaming the subject). For instance, in the sentence “She is an artist,” the word “artist” is the subject complement as it provides information about the subject “she,” specifically, her profession.
Finally, adverbial complements modify the verb by providing additional information such as time, place, manner, or condition. They answer questions such as “when,” “where,” “how,” or “why.” Consider the sentence “He ran to the park yesterday.” The word “yesterday” is the adverbial complement, as it specifies the time of the action.
It is important to note that not all verbs require complements. Some verbs, known as intransitive verbs, do not transfer their action onto an object or require additional information to complete the meaning. For example, in the sentence “She runs,” the verb “runs” does not require a complement.
Moreover, complements can also be found in other parts of speech, such as prepositions and adjectives. Prepositional complements occur when a preposition is followed by a noun phrase or pronoun. For instance, in the sentence “He is interested in art,” the phrase “in art” acts as the prepositional complement as it completes the meaning of the preposition “in.”
Adjectival complements, on the other hand, occur when an adjective is followed by another word or phrase that adds information about the noun it modifies. For example, in the sentence “The cake smells delicious,” the word “delicious” is the adjectival complement as it further describes the noun “cake.”
In conclusion, a complement in grammar analysis is a word, phrase, or clause that provides necessary information to complete the meaning of a sentence. Whether it is an object complement, subject complement, adverbial complement, prepositional complement, or adjectival complement, each type serves a vital role in enhancing the overall structure and depth of a sentence. Understanding the meaning and various types of complements is essential in mastering the complexities of grammar analysis and effectively communicating in the English language.
