Definition of Object of a Preposition

The object of a preposition is a noun, pronoun, gerund, or clause that follows a preposition and completes its meaning. In simpler terms, it’s the word or group of words that the preposition is referring to. The preposition and its object together form a prepositional phrase, which functions as either an adjective or an adverb in a sentence. Understanding this relationship is essential for grasping sentence structure and meaning.

To further clarify, a preposition itself is a word that shows the relationship between a noun or pronoun and other words in the sentence. Common examples of prepositions include: in, on, at, to, from, with, by, about, under, over, of, for, before, after, during, since, through, behind, between, among. The object of the preposition is always located after the preposition within the prepositional phrase.

Consider the sentence: “The book is on the table.” Here, “on” is the preposition, and “the table” is the object of the preposition. The entire phrase “on the table” acts as an adverbial phrase, modifying the verb “is” by telling us where the book is located.

Structural Breakdown

The structure of a prepositional phrase is straightforward: it consists of a preposition followed by its object. The object can be a single word or a group of words acting as a single unit. Let’s break down the components:

1. Preposition: This is the word that establishes the relationship (e.g., in, on, at, to, from).
2. Object of the Preposition: This is the noun, pronoun, gerund, or clause that the preposition refers to.

Here’s a visual representation:

[Preposition] + [Object of the Preposition] = Prepositional Phrase

Let’s look at some examples to illustrate this structure:

• With me: “With” is the preposition, and “me” is the object (a pronoun).
• In the garden: “In” is the preposition, and “the garden” is the object (a noun phrase).
• Before leaving: “Before” is the preposition, and “leaving” is the object (a gerund).
• About what happened: “About” is the preposition, and “what happened” is the object (a clause).

Understanding this basic structure is crucial for identifying prepositional phrases and their function within a sentence. The prepositional phrase can act as an adjective, modifying a noun or pronoun, or as an adverb, modifying a verb, adjective, or another adverb.

For example:

• Adjective Phrase: “The house with the blue door is beautiful.” (Modifies the noun “house”)
• Adverb Phrase: “He walked to the store.” (Modifies the verb “walked”)

Types and Categories

The object of a preposition can take various forms, depending on the type of word or phrase that follows the preposition. The most common types are nouns, pronouns, gerunds, and clauses.

Let’s explore each of these in detail.

Noun Objects

A noun is the most common type of object of a preposition. It represents a person, place, thing, or idea.

The noun can be a single word or a noun phrase (a group of words that functions as a noun).

Examples:

• At the park
• On the table
• With his friend
• Behind the building
• During the meeting

Pronoun Objects

A pronoun is a word that replaces a noun. When a pronoun is the object of a preposition, it must be in the objective case (me, him, her, us, them, it, whom).

Subjective pronouns (I, he, she, we, they, it, who) cannot be used as objects of prepositions.

Examples:

• To me
• With him
• For her
• Between us
• About them

Gerund Objects

A gerund is a verb ending in “-ing” that functions as a noun. It can be the object of a preposition when the action of the verb is being referred to as a thing or activity.

Examples:

• By studying
• After eating
• Before leaving
• In learning
• Without thinking

Clause Objects

A clause is a group of words containing a subject and a verb. A clause can function as the object of a preposition, typically introduced by words like “what,” “that,” “who,” “where,” “when,” “why,” or “how.”

Examples:

• About what happened
• On what she said
• Depending on how you feel
• According to what the news reported
• Regardless of who wins

Usage Rules

Proper usage of objects of prepositions involves several key rules:

1. Case of Pronouns: Always use the objective case (me, him, her, us, them, whom) for pronouns that are objects of prepositions.
2. Word Order: The object of the preposition always follows the preposition.
3. Clarity: Ensure the object of the preposition is clear and unambiguous.
4. Correct Preposition: Choose the correct preposition to convey the intended meaning.

Let’s elaborate on each rule with examples:

1. Case of Pronouns: It’s crucial to use the correct pronoun case. For instance, it’s correct to say “The gift is for her,” but incorrect to say “The gift is for she.” The pronoun “her” is in the objective case, while “she” is in the subjective case.
2. Word Order: The preposition always comes before its object. “In the garden” is correct; “The garden in” is not.
3. Clarity: The object should be easily identifiable. Avoid vague or ambiguous references. For example, instead of saying “He talked about it,” specify what “it” refers to: “He talked about the project.”
4. Correct Preposition: Selecting the correct preposition is vital for meaning. “He arrived at the airport” is different from “He arrived to the airport.” The former is correct, while the latter is grammatically incorrect.

Common Mistakes

Several common mistakes can occur when using objects of prepositions. Being aware of these errors can help you avoid them in your own writing and speech.

1. Incorrect Pronoun Case: Using subjective pronouns instead of objective pronouns as objects of prepositions is a frequent error.
2. Misplaced Preposition: Placing the preposition in the wrong position in the sentence can lead to confusion.
3. Vague Object Reference: Using unclear or ambiguous objects can obscure the meaning of the sentence.
4. Incorrect Preposition Choice: Choosing the wrong preposition can alter the intended meaning or create grammatically incorrect sentences.

Here’s a table illustrating these common mistakes and their corrections:

Incorrect	Correct	Explanation
The gift is for she.	The gift is for her.	Using the subjective pronoun “she” instead of the objective pronoun “her.”
The garden in he was walking.	He was walking in the garden.	Misplacing the preposition “in” after the object “the garden.”
He talked about it.	He talked about the new project.	Using the vague pronoun “it” instead of a specific noun phrase “the new project.”
He arrived to the airport.	He arrived at the airport.	Using the incorrect preposition “to” instead of “at.”
Between you and I, this is a secret.	Between you and me, this is a secret.	Using the subjective pronoun “I” instead of the objective pronoun “me” after the preposition “between”.
She depended of her parents.	She depended on her parents.	Using the incorrect preposition “of” instead of “on” after the verb “depended.”

Advanced Topics

For advanced learners, understanding the nuances of objects of prepositions in complex sentences can be beneficial. This includes recognizing elliptical constructions and understanding how prepositional phrases can be embedded within other phrases.

Elliptical Constructions: In some cases, the object of the preposition might be omitted if it is understood from the context. For example, “He went to the store, and I went, too” implies “I went to the store, too,” where “the store” is the understood object of the preposition “to.”

Embedded Prepositional Phrases: Prepositional phrases can be embedded within other phrases, creating complex sentence structures. For instance, “The book on the table in the corner is mine” contains two prepositional phrases: “on the table” (modifying “book”) and “in the corner” (modifying “table”).

Recognizing these advanced constructions can help you analyze and understand complex sentences with greater accuracy.

FAQ

Here are some frequently asked questions about objects of prepositions:

1. What is the difference between a subject and an object of a preposition?

   The subject performs the action of the verb, while the object of a preposition is the noun, pronoun, gerund, or clause that follows the preposition and completes its meaning. The subject is typically found before the verb, while the object of the preposition is found after the preposition.

2. Can a preposition have more than one object?

   Yes, a preposition can have multiple objects connected by conjunctions such as “and” or “or.” For example: “He spoke to John, Mary, and Susan.” Here, “John,” “Mary,” and “Susan” are all objects of the preposition “to.”

3. How do I identify the object of a preposition in a complex sentence?

   First, identify the prepositions in the sentence. Then, determine which noun, pronoun, gerund, or clause immediately follows each preposition and completes its meaning. This is the object of the preposition. Remember to consider context and sentence structure.

4. Can a verb be the object of a preposition?

   No, a verb cannot be the object of a preposition. However, a gerund (a verb ending in “-ing” that functions as a noun) can be the object of a preposition. For example: “He is good at swimming.”

5. What is the function of a prepositional phrase in a sentence?

   A prepositional phrase functions as either an adjective (modifying a noun or pronoun) or an adverb (modifying a verb, adjective, or another adverb). It provides additional information about the elements in the sentence.

6. Why is it important to understand objects of prepositions?

   Understanding objects of prepositions is crucial for constructing grammatically correct and meaningful sentences. It helps ensure clarity and precision in your writing and speech, improving your overall communication skills.

7. Can a clause be the object of a preposition? If so, how can I identify it?

   Yes, a clause can indeed be the object of a preposition. These clauses often begin with words like “what,” “that,” “who,” “where,” “when,” “why,” or “how.” To identify it, look for a group of words containing a subject and a verb that follows the preposition and completes its meaning. For example, in the sentence “She is worried about what might happen,” the clause “what might happen” is the object of the preposition “about.”

8. Are there any prepositions that are often confused with adverbs? How can I tell the difference?

   Yes, some words can function as both prepositions and adverbs, such as “around,” “above,” “below,” “inside,” “outside,” and “near.” To distinguish between them, check if the word is followed by a noun or pronoun. If it is, it’s a preposition, and the noun or pronoun is its object. If it’s not followed by a noun or pronoun, it’s an adverb. For instance, in “The cat is inside the house,” “inside” is a preposition. In “The cat is inside,” “inside” is an adverb.

Conclusion

Understanding the object of a preposition is fundamental to mastering English grammar. By grasping the definition, structure, types, and usage rules, you can significantly improve the clarity and accuracy of your writing and speech.

Remember to pay attention to pronoun case, word order, and preposition choice to avoid common mistakes.
