Conjunction Vs Preposition: Understanding the Fundamental Differences

The English language contains an abundance of grammar rules that need to be understood and executed with perfection. While the grammatical concepts aren’t rocket science, they require minute attention to details, especially in distinguishing between conjunctions and prepositions.

Conjunctions and prepositions, both are known as connectors, but they have profound differences that are essential to an understanding in writing, reading, and communication. In this article, we will focus on the fundamental differences between conjunctions and prepositions.

What is a Conjunction?

A conjunction is a word that connects words, phrases, and clauses to form a sentence. It is used to join two or more ideas or thoughts.

Types of Conjunctions

· Coordinating Conjunctions

Coordinating conjunctions join words, phrases, or independent clauses of equal importance. The most common coordinating conjunctions in English are and, but, or, nor, so, for and yet.


– I like to read novels, but I prefer to write poems
– My bike is red and my sister’s bike is blue.

· Subordinating Conjunctions

Subordinating conjunctions join subordinate clauses (dependent clauses) to main clauses (independent clauses) to show the relationship between the two.


– As soon as she arrived at the airport, she realized she had left her passport at home.
– I’ll come early to the class since I have to meet the teacher.

What is a Preposition?

A preposition is a word that shows the relationship between a noun or pronoun and other words in a sentence. It shows the position or direction of the noun or pronoun in relation to other words in the sentence.

Types of Prepositions

· Time Prepositions

Time prepositions show the timing of an event or an action. The most commonly used time prepositions are ‘at’, ‘on’, and ‘in’.


– The party is at 8 PM
– I will see you on Friday
– I will reach home in five minutes

· Space Prepositions

Space prepositions show the position or direction of nouns and pronouns in relation to other words in a sentence. Examples of space prepositions are ‘above’, ‘below’, ‘near’, ‘beside’, and ‘in’.

Conjunction Vs Preposition: The Fundamental Differences

While conjunctions and prepositions serve a similar purpose of connecting words or phrases, they have significant differences in their function, structure, and usage.

· Function

Conjunctions connect words or clauses together, whereas prepositions connect the noun or pronoun to other words in the sentence.


Conjunction- She sings and dances beautifully
Preposition- The book is on the table.

· Structure

Conjunctions are standalone words that connect the sentence whereas prepositions typically followed by a noun, pronoun, or gerund.


Conjunction- I like to eat ice cream and cake
Preposition- I am thinking about going on vacation

Conjunctions typically join words, phrases, or clauses together that have equal importance, while prepositions show the relationship between the noun or pronoun and other words in the sentence.

While conjunctions and prepositions may seem similar, they are different connectors in the English language.
