Conjunctions are a part of speech that helps sentences flow smoothly. It connects words, phrases, and clauses so ideas feel clear and complete instead of short and choppy. In this guide, we explain what a conjunction is in grammar, the main types of conjunctions, and clear examples you can use in your own writing.

What is a Conjunction in Grammar?

First, let’s define conjunction

Before we delve into the different conjunction types and examples, let's first understand the fundamental definition of a conjunction.

In grammar, a conjunction is one of the eight parts of speech in the English language. Its main job is to link parts of a sentence so ideas connect clearly.

CONJUNCTION DEFINITION

What is a conjunction in grammar?

conjunction is a part of speech in English grammar that connects words, phrases, or clauses. This answers common questions such as what is a conjunction, what a conjunction means, and what does the word conjunction mean.

A conjunction works like a bridge between ideas, helping sentences and paragraphs feel complete and easy to read. Conjunctions can join similar elements such as two nouns, two verbs, or two adjectives. They can also connect entire clauses to form longer sentences.

Examples of conjunctions in sentences:

  • “I like apples and oranges.”
  • “We stayed inside because it was raining.”
  • “You can choose either tea or coffee.”

Types of Conjunctions

Types of Conjunctions

Conjunctions, which are crucial for connecting words, phrases, and clauses, can be categorized into three main types:

  • Coordinating conjunctions
  • Subordinating conjunctions
  • Correlative conjunctions
Types of Conjunction Examples Coordinating Subordinating and Correlative Conjunctions

Types of conjunctions used in grammar

Each type serves a specific purpose in sentence structure. Below are conjunctions in sentences examples that show how each type works in practice.

What is a conjunction - Types of Conjunctions with Examples

Each type serves a distinct purpose in sentence structure and plays a vital role in conveying meaning and coherence in written and spoken language. 

Coordinating conjunctions

Coordinating conjunctions join words, phrases, or clauses that are grammatically equal. In other words, they connect two or more items of the same kind. 

The seven coordinating conjunctions are often remembered using the acronym FANBOYS:

  • For
  • And
  • Nor
  • But
  • Or
  • Yet
  • So


A sentence with a coordinating conjunction would be: “I wanted to go to the park, but it was raining.”

Subordinating conjunctions

Subordinating conjunctions are used to link a subordinate (or dependent clause) to a main clause (or independent clause), creating a complex sentence

Examples include words like because, although, when, while, if, and since. 

For instance, "Although it was raining, we decided to go out."

Correlative conjunctions

Correlative conjunctions are pairs of conjunctions that work together to coordinate words or phrases. 

These pairs include either/or, neither/nor, both/and, not only/but also, whether/or. 

For example, in the sentence "Either you finish your homework, or you don't get to play video games," the pair 'either/or' is a correlative conjunction setting up a choice between two alternatives.

When to use each type of conjunction:

Use Conjunctions to Improve Flow

If you're not using conjunctions, writing can sound repetitive. By connecting ideas, phrases, and clauses, conjunctions can help your writing sound more natural and less disjointed. 

As The Editor’s Manual explains, “conjunctions link words, phrases, clauses, and sentences, and show a logical relation between them.”

According to the Chicago Manual of Style, as many as 10% of sentences in polished, professional writing begin with conjunctions such as and, but, or so. This shows that conjunctions are not only grammatically correct, but also commonly used to improve sentence flow and emphasis.

Examples:

  • Without conjunction: "I love to read. I also love to write."
  • With conjunction: "I love to read, and I also love to write."
Avoid Overusing Conjunctions

While conjunctions are essential, it's crucial to avoid overusing them, as this can make your sentences long and confusing. It's better to keep your sentences simple and clear.

Example:

  • Without conjunction: "I went to the store, and I bought apples, and I also got some oranges, and I paid with cash."
  • With conjunction: "I went to the store. I bought apples and oranges and paid with cash."
Choose the Correct Type of Conjunction

When you're ready to pick a conjunction to use in your sentences, just remember:

  • Use coordinating conjunctions to connect equal ideas
  • Use subordinating conjunctions to link dependent and independent clauses
  • Use correlative conjunctions to show pairs or choices


Examples:

  • Coordinating: "I love apples and oranges."
  • Subordinating: "We played outside until it got dark."
  • Correlative: "Either you clean your room, or you can't go to the party."


Conjunctions do more than connect ideas. They also show how ideas relate to each other such as the examples shown below:

Common Conjunction Mistakes

Common conjunction mistakes

Even though conjunctions are simple, they are often misused. As the grammar expert Professor Scott Mendoza explains, they connect ideas, control flow, and help readers follow your meaning. When used incorrectly, these small words can distort logic or leave your message unclear.

Here are a few common mistakes to avoid.

Comma Splices

A comma splice happens when two independent clauses are joined with only a comma.

  • Incorrect: “I wanted to leave, I was tired.”
  • Correct: “I wanted to leave, because I was tired.”
Starting Too Many Sentences With And or But 

Starting sentences with and or but is not always wrong, but overusing them can weaken your writing.

Research on student writing shows how frequently conjunctions appear in real sentences. In one academic study, writers used an average of 23.49 conjunctions per essay, with additive conjunctions like and and but appearing most often. This high frequency helps explain why conjunction mistakes are so common.

Parts of Speech

Conjunctions vs other parts of speech

Conjunctions are sometimes confused with other parts of speech or subject in grammar, especially prepositions and adverbs.

  • Conjunctions connect words or clauses 
  • Prepositions show relationships between a noun and another word
  • Adverbs modify verbs, adjectives, or other adverbs 


Understanding these differences helps avoid grammar errors.
