Compound Sentences

What is a Compound Sentence ?

A compound sentence is formed when two independent clauses are linked together, 
usually using coordinating conjunctions such as "and" or "but."

It works best when integrating two or more sentences that are independent yet connected into a single, coherent sentence.
For example,

Example

Following are two simple sentences. Both of these sentences can be used independently.

    Simple Sentence : I want to go on vacation.
     Simple Sentence : I need to take a leave from work.

When we combine them using Coordinating conjunction but it will become a compound sentence.

    Compound Sentence

I want to go on vacation, but I need to take a leave from work.

Understanding Compound Sentences

A compound sentence is formed by combining two or more independent clauses using coordinating conjunctions or semicolons.
The key characteristic of a compound sentence is that it contains multiple ideas, each capable of standing alone as a separate sentence. When these separate sentences are integrated, they provide a link between similar or opposing ideas, making the writing more sophisticated and engaging.

Structure of Compound Sentences

Compound sentences are easy to identify because they usually use a coordinating conjunction and a semicolon to connect two clauses.

Example

independent clause, coordinating conjunction independent clause
independent clause; independent clause

Coordinating Conjunctions: FANBOYS

The most common way to create a compound sentence is by using coordinating conjunctions, which you may remember as FANBOYS: For, And, And, Nor, But , Or, Yet , So.
These conjunctions help in establishing the connection between the ideas in each independent clause.

Example

It is too late so we cannot go to the cinema.
He applied for the job and got it.

For

We use the conjunction “for” (which means “because”) to join two clauses when the second clause is the cause of the first clause.

Example

Some people are avoiding vaccines***, for*** they think vaccines might have side effects.

And

The ‘and’ conjunction is the most common conjunction. It has a wide range of uses. We use "and" to join two equally important sentences.

London is in England, and Rome is in Italy.

Use “and” to join two sentences when the second sentence occurs after the first sentence.

Example

There was a loud bang, and the lights went out.

If the second sentence is the result of the first, use "and" to link them.

Example

He went to bed early, and the next day he felt better.

Nor

If the first sentence contains a negative phrase such as no or never, we use the conjunction 'nor' to join the two alternative sentences. In this case, both sentences are false or do not occur.

Example

He will travel neither by subway nor by flights. He never went to Italy nor will go.

But

We use the conjunction “but” to add a sentence that contradicts the previous clause.

Example

Mary ran fast, but she couldn’t catch the train.

Or

We use the conjunction “or” to connect two alternative sentences.

Example

Please let me know if you prefer pizza or pasta for dinner.

Yet

The conjunction ‘yet’ is similar to the conjunction “but” or “nevertheless”. It shows a contrast with the first part of the sentence.

Example

It is completely waterproof, yet light and comfortable.

So

We use the conjunction “so” to join two sentences when the first clause is the reason for the second clause. it indicates “as a result of” or “for this reason” or something like therefore.

Example

It might rain, so take an umbrella.

Semicolons

Another way to form a compound sentence is by using a semicolon to separate two related independent clauses. This method emphasizes the close connection between the ideas.

Example

Sarah has always been passionate about art; she spends hours creating beautiful paintings.

Semicolons with Conjunctive Adverbs

We can also link independent clauses using conjunctive adverbs like however, therefore, furthermore, nevertheless. The conjunctive adverb must be preceded by a semicolon (;) and followed by a comma (,).

Example

The exam was challenging; nevertheless, she managed to score the highest marks.
