To understand and effectively use English sentences, one must master various grammatical elements and their applications. Among them, the complement and the past participle (p.p.) object complement are topics that many learners find challenging. In this article, we will provide an in-depth explanation of the role of complements in English sentences, the definition and usage of the past participle (p.p.), and the object complement.
1. What is a complement?
A complement is a component of a sentence that provides additional information about the subject or object. In simple terms, it describes the state or characteristic of the subject, or the object. Complements can be divided into subject complements and object complements.
1.1. Subject complement
A subject complement connects with the subject and describes the state or nature of the subject. Subject complements are usually made up of nouns or adjectives and are used with a ‘be verb’ to connect to the subject. For example,
“She is a teacher.” here, “a teacher” is the subject complement. This sentence describes what profession the subject ‘She’ has.
1.2. Object complement
An object complement provides additional information about the verb’s object. This complement can also exist in the form of nouns, adjectives, and various other forms. For example,
“We consider him a genius.” where “a genius” is the object complement, explaining the object ‘him’.
2. What is a past participle (p.p.)?
The past participle is a form of the verb that is primarily used to indicate the perfect tense or the passive voice. Past participles can be divided into regular verbs and irregular verbs, with regular verbs typically formed by adding ‘-ed’. For instance, ‘play’ becomes ‘played’. Irregular verbs have different forms that must be memorized.
For example, ‘go’ becomes ‘gone’, and ‘have’ becomes ‘had’.
2.1. Uses of the past participle
In English, past participles are used for various purposes. The most common use is to form perfect tenses or to express the state of the subject in passive voice sentences.
3. Object complement
An object complement is a type of complement that provides additional information about the object’s verb. In particular, the object complement in the form of a past participle (p.p.) is used to explain what action or state the subject represents regarding the object. For example,
“I found the book interesting.” where ‘the book’ is the object, and ‘interesting’ is the object complement that provides explanation about that object.
3.1. Examples of object complements
Object complements are primarily used with the following types of verbs:
– Sensory verbs (see, hear, feel, etc.)
– Causative verbs (make, let, have, etc.)
– Others (consider, find, think, etc.)
3.2. Past participles as object complements
Object complements in the form of past participles are often used to emphasize the state or characteristic of the subject. For example,
“They left the door closed.” here, ‘the door’ is the object, and ‘closed’ is the object complement that describes its state. This sentence emphasizes that the door is closed in context.
4. Sentence structure with object complements
Sentences that include an object complement generally have the following structure:
Subject + Verb + Object + Object Complement
For example, “They made him happy.” here, ‘They’ is the subject, ‘made’ is the verb, ‘him’ is the object, and ‘happy’ is the object complement. This sentence conveys the meaning that they made ‘him’ happy.
5. Importance of complements in English
Complements are essential elements that clarify the meaning of sentences in English. Without complements, sentences may be incomplete or difficult to interpret. Incorrect use of complements can lead to communication errors, so it is essential to learn the various uses of complements in studying English.
