Prepositions are essential components of English grammar, linking nouns, pronouns, and phrases to other words within a sentence. They can often be confusing for language learners, especially when it comes to prepositions of cause and purpose. This article aims to shed light on these specific types of prepositions, providing clear definitions, examples, and practical tips to help you master their usage.
Understanding Prepositions of Cause
Prepositions of cause are used to show the reason behind an action or event. They help to explain why something happens. Below are the most commonly used prepositions of cause:
Because of
The preposition “because of” is used to indicate the reason for something. It is usually followed by a noun or a pronoun.
**Examples:**
– She missed the meeting because of the heavy traffic.
– He couldn’t attend the class because of his illness.
In both examples, “because of” introduces the reason for the action mentioned in the main clause.
Due to
“Due to” functions similarly to “because of” and is often used interchangeably. However, “due to” is generally considered more formal and is often used in written English.
**Examples:**
– The flight was canceled due to bad weather.
– The project was delayed due to technical difficulties.
It’s worth noting that “due to” is more commonly used after the verb “to be.”
Owing to
“Owing to” is another formal preposition of cause. It is often used in academic or formal writing and serves the same function as “because of” and “due to.”
**Examples:**
– The event was postponed owing to unforeseen circumstances.
– The company faced financial difficulties owing to a decrease in sales.
On account of
“On account of” is a slightly less formal preposition of cause, often used in both spoken and written English.
**Examples:**
– The game was canceled on account of the rain.
– He was late on account of a traffic jam.
Understanding Prepositions of Purpose
Prepositions of purpose indicate the goal or intention behind an action. They help to explain why someone does something or what they aim to achieve. The most commonly used prepositions of purpose include “for,” “to,” “in order to,” and “so as to.”
For
The preposition “for” is used to indicate the purpose of an action. It is usually followed by a noun or a gerund (verb + ing).
**Examples:**
– She went to the store for some milk.
– He is studying hard for his exams.
In these sentences, “for” introduces the purpose of the action.
To
The preposition “to” is used to express purpose and is often followed by the base form of a verb.
**Examples:**
– She went to the library to study.
– He is saving money to buy a new car.
In these examples, “to” connects the action with its intended purpose.
In order to
“In order to” is a more formal way of expressing purpose. It is often used in written English and is followed by the base form of a verb.
**Examples:**
– She is taking extra classes in order to improve her skills.
– He moved to a new city in order to find better job opportunities.
Using “in order to” often emphasizes the intention behind the action.
So as to
“So as to” is another formal preposition of purpose, used similarly to “in order to.” It is also followed by the base form of a verb.
**Examples:**
– She left early so as to avoid traffic.
– He spoke softly so as to not wake the baby.
Common Mistakes and How to Avoid Them
Understanding the nuances of prepositions of cause and purpose can be challenging, and even advanced learners sometimes make mistakes. Here are some common errors and tips on how to avoid them:
Confusing “because of” and “due to”
While “because of” and “due to” are often used interchangeably, they are not always appropriate in the same contexts. “Because of” is typically used to modify verbs, while “due to” is often used after the verb “to be.”
**Incorrect:**
– The project was delayed because of technical difficulties.
**Correct:**
– The project was delayed due to technical difficulties.
**Incorrect:**
– He couldn’t attend the class due to his illness.
**Correct:**
– He couldn’t attend the class because of his illness.
Using “for” incorrectly with verbs
“For” should be followed by a noun or a gerund, not the base form of a verb.
**Incorrect:**
– She went to the store for buy some milk.
**Correct:**
– She went to the store for buying some milk.
– She went to the store to buy some milk.

Advanced Usage and Nuances
Once you’ve mastered the basics, it’s important to understand some of the more advanced nuances and variations in the usage of prepositions of cause and purpose.
“For” + noun vs. “to” + verb
While both “for” and “to” can be used to express purpose, they are used differently. “For” is followed by a noun or a gerund, while “to” is followed by the base form of a verb.

“Because of” vs. “because”
“Because of” is a preposition and is followed by a noun or a pronoun, while “because” is a conjunction and is followed by a clause.
**Example:**

– She missed the meeting because there was heavy traffic. (Conjunction + clause)
Combining Prepositions of Cause and Purpose
In more complex sentences, you may need to use both prepositions of cause and purpose. Understanding how to combine them correctly can add depth and clarity to your communication.
**Example:**
– She is studying hard because of her upcoming exams in order to pass with flying colors.
In this sentence, “because of” explains the reason for her studying, while “in order to” explains the purpose.
