Definition of Prepositions

A preposition is a word that connects a noun, pronoun, or noun phrase to other words in a sentence. It typically indicates the relationship of the noun or pronoun to a place, time, direction, or other concept. The word or phrase that the preposition introduces is called the object of the preposition. Together, the preposition and its object form a prepositional phrase, which functions as an adjective or adverb modifying another word in the sentence.

Prepositions are essential for providing context and clarity. They specify the location, time, or manner in which an action occurs or a state exists. Without prepositions, sentences would lack crucial details, making it difficult to understand the intended meaning. For example, consider the sentence “The book is the table.” This sentence is incomplete and unclear. By adding a preposition, such as “on,” we create the sentence “The book is on the table,” which clearly indicates the book’s location.

Prepositions can be classified based on their function and the type of relationship they express. Common categories include prepositions of time (at, on, in), prepositions of place (at, on, in, under, over), and prepositions of movement (to, from, through, across). Understanding these different categories helps learners choose the correct preposition to express the intended meaning.

Structural Breakdown of Prepositional Phrases

The structure of a prepositional phrase is relatively simple: it consists of a preposition followed by its object. The object of the preposition is typically a noun, pronoun, or noun phrase. The entire prepositional phrase then functions as an adjective or adverb, modifying another word in the sentence.

Here’s a breakdown of the structure:

Preposition + (Modifiers) + Object of the Preposition

Let’s examine some examples to illustrate this structure:

• On the table (preposition + object)
• In the big box (preposition + modifier + object)
• With him (preposition + pronoun)
• After eating dinner (preposition + gerund phrase)

In these examples, the preposition establishes the relationship between the object and another element in the sentence. The prepositional phrase then provides additional information about that element. For instance, in the sentence “The cat slept on the mat,” the prepositional phrase “on the mat” modifies the verb “slept,” indicating where the cat was sleeping.

It is important to note that the object of the preposition can be a single word or a phrase. It can also be a gerund (a verb ending in “-ing” that functions as a noun). Understanding the structure of prepositional phrases is crucial for correctly interpreting and constructing sentences in English.

Types of Prepositions

Prepositions can be categorized based on the type of relationship they express. Here are some of the most common categories:

Prepositions of Time

Prepositions of time indicate when something happens. The most common prepositions of time are at, on, and in. However, there are many other prepositions that can be used to express time, such as before, after, during, until, since, and for.

Here’s a summary of how at, on, and in are typically used:

• At: Used for specific times (e.g., at 3:00 PM, at noon, at night)
• On: Used for specific days or dates (e.g., on Monday, on July 4th, on my birthday)
• In: Used for longer periods of time, such as months, years, seasons, or centuries (e.g., in July, in 2023, in the summer, in the 21st century)

Prepositions of Place

Prepositions of place indicate where something is located. Common prepositions of place include at, on, in, under, over, beside, between, behind, and in front of.

Here’s a summary of how at, on, and in are typically used to indicate place:

• At: Used for specific locations or addresses (e.g., at the library, at 123 Main Street, at the corner)
• On: Used for surfaces (e.g., on the table, on the wall, on the floor)
• In: Used for enclosed spaces or areas (e.g., in the box, in the garden, in the city)

Prepositions of Movement

Prepositions of movement indicate how something moves from one place to another. Common prepositions of movement include to, from, through, across, into, onto, out of, and around.

These prepositions often describe the path or direction of movement. For example:

• The bird flew to the tree.
• She walked across the street.
• The car drove through the tunnel.

Prepositions of Manner

Prepositions of manner describe how something is done. Common prepositions of manner include by, with, and in.

Examples:

• He opened the door with a key.
• She traveled by train.
• They spoke in a whisper.

Prepositions of Purpose

Prepositions of purpose indicate the reason or intention behind an action. Common prepositions of purpose include for.

Examples:

• He went to the store for milk.
• She studies hard for good grades.

Prepositions of Reason

Prepositions of reason explain the cause of something. Common prepositions of reason include because of, due to, and on account of.

Examples:

• The game was canceled because of the rain.
• He was late due to a traffic jam.

Prepositions of Possession

Prepositions of possession indicate ownership or belonging. The most common preposition of possession is of.

Examples:

• The cover of the book is torn.
• The president of the company announced new policies.

Usage Rules for Prepositions

Using prepositions correctly can be challenging, as their usage often depends on context and idiomatic expressions. Here are some important rules to keep in mind:

Prepositions at the End of Sentences

It is generally acceptable to end a sentence with a preposition, especially in informal English. This often occurs when the object of the preposition is a relative pronoun (who, which, that) that is omitted or when the preposition is part of a phrasal verb.

Examples:

• “Who are you talking to?” (The object of the preposition is “whom,” which is implied.)
• “What are you looking at?” (The object of the preposition is “what.”)
• “This is the house I grew up in.” (The object of the preposition is “which,” referring to the house.)

While some grammar purists may frown upon ending sentences with prepositions, it is a common and natural construction in modern English.

Prepositions with Gerunds

When a verb follows a preposition, it should be in the gerund form (i.e., the “-ing” form). This is because the gerund functions as a noun, and prepositions are followed by nouns or noun phrases.

Examples:

• “I am good at playing the piano.” (Not “I am good at play the piano.”)
• “She is interested in learning new languages.” (Not “She is interested in learn new languages.”)
• “Thank you for helping me.” (Not “Thank you for help me.”)

Fixed Prepositions

Some verbs, nouns, and adjectives are always followed by specific prepositions. These are called fixed prepositions or dependent prepositions. It is important to memorize these combinations, as using the wrong preposition can change the meaning of the sentence or make it grammatically incorrect.

Examples:

• “I agree with you.” (Not “I agree to you.”)
• “She is afraid of spiders.” (Not “She is afraid from spiders.”)
• “He is dependent on his parents.” (Not “He is dependent of his parents.”)

A table of common fixed preposition combinations:

Word	Preposition	Example
Agree	With	I agree with your opinion.
Afraid	Of	She is afraid of heights.
Dependent	On	He is dependent on his family.
Interested	In	They are interested in history.
Good	At	She is good at playing chess.
Similar	To	This car is similar to that one.
Different	From	His idea is different from mine.
Responsible	For	He is responsible for the project.
Aware	Of	They are aware of the risks.
Excited	About	She is excited about the trip.
Believe	In	I believe in his abilities.
Apply	For	He applied for the job.
Complain	About	They complained about the service.
Succeed	In	She succeeded in her career.
Protect	From	The helmet protects you from injury.

Common Mistakes with Prepositions

Prepositions can be tricky, and even advanced learners make mistakes. Here are some common errors to watch out for:

• Incorrect preposition choice: Using the wrong preposition for a specific context.
  • Incorrect: “I am interested on learning new languages.”
  • Correct: “I am interested in learning new languages.”
• Omitting prepositions: Leaving out a necessary preposition.
  • Incorrect: “I went store.”
  • Correct: “I went to the store.”
• Unnecessary prepositions: Adding a preposition when it is not needed.
  • Incorrect: “Where are you going to?”
  • Correct: “Where are you going?”
• Using “of” instead of “have” after modal verbs: This is a common spoken error.
  • Incorrect: “I should of gone to the party.”
  • Correct: “I should have gone to the party.”

By being aware of these common mistakes, you can improve your accuracy and avoid errors in your writing and speaking.

Advanced Topics in Prepositions

For advanced learners, here are some more complex aspects of prepositions to explore:

Complex Prepositions

Complex prepositions, also known as phrasal prepositions, consist of two or more words that function as a single preposition. These prepositions often express more nuanced relationships than simple prepositions.

Examples of complex prepositions include: according to, because of, in spite of, on account of, in addition to, instead of, with regard to, and in front of.

Here are some example sentences using complex prepositions:

• “According to the weather forecast, it will rain tomorrow.”
• “The game was canceled because of the heavy rain.”
• “In spite of the difficulties, they succeeded.”
• “On account of his illness, he could not attend the meeting.”
• “In addition to English, she speaks French.”
• “Instead of going to the movies, we stayed home.”
• “With regard to your question, I will answer it later.”
• “The car is parked in front of the building.”

Prepositional Verbs

Prepositional verbs consist of a verb followed by a preposition. The preposition changes the meaning of the verb, creating a new verb phrase with a distinct meaning. It’s crucial to treat the verb and preposition as a single unit.

Examples of prepositional verbs include: look at, listen to, wait for, depend on, agree with, and believe in.

Here are some example sentences using prepositional verbs:

• “Please look at the picture.”
• “I like to
