Conjunctions, also called connecting or linking words, are words like and, or, so and when. We use them to join words, phrases and clauses. Coordinating conjunctions, such as and, or, but join two words, phrases or independent clauses together. Subordinating conjunctions, such as after, although, so or as, join an independent clause with a dependent or subordinate one.
Learn about coordinating and subordinating conjunctions in English grammar then practice using them in the exercises at the end of the lesson.
It is Jane’s birthday so she is having a party. Lots of people are coming, but not all of our friends have been invited.
Although the traffic was bad, we arrived at the party on time. Jane was happy about the chocolates and flowers we gave her.
When she put music on, people started dancing immediately. Since the music was so great, we danced all night long.
Coordinating conjunctions connect two words, phrases or clauses of the same grammatical type. We use them to connect two ideas of equal value. Common coordinating conjunctions include and, but, or.
- What should we give Jane for her birthday, flowers or chocolate? (connecting words)
- Her birthday party will be very fun and full of people. (connecting phrases)
- Lots of people are coming but not all of our friends were invited. (connecting clauses)
- Jane’s birthday is on Friday. But the party is on Saturday. (connecting sentences)
- In formal written English, it’s considered incorrect to start a sentence with a conjunction.
Use the mnemonic FANBOYS to help you remember which conjunctions are coordinating.
- F → for
A → and
N → nor
B → but
O → or
Y → yet
S → so
List of Coordinating Conjunctions
Coordinating conjunctions can be divided into categories based on their meaning or function in a sentence: addition, alternative, contrast or cause/reason/result. The table below provides an overview.
|addition||and||We gave Jane flowers and chocolate for her birthday.|
|alternative||or||Should we give Jane flowers or chocolate?|
|nor||We didn’t buy Jane flowers(,) nor did we buy her a present.|
|contrast||but||We bought flowers(,) but we did not buy chocolate.|
|yet||We bought flowers for Jane(,) yet we did not buy chocolate.|
|cause/reason/result||for||We bought Jane flowers, for it was her birthday.|
|so||It’s Jane’s birthday, so we bought her flowers.|
Word Order with Coordinating Conjunctions
A coordinating conjunction always comes between the two elements it connects i.e. in the mid position.
- Lots of people are coming to the party, but not all of our friends are coming.
But not all of our friends are coming, lots of people are coming.
Because coordinating conjunctions connect words, phrases and clauses of the same grammatical type (coordinating clauses), we can switch the order of the things being connected without changing the meaning.
- Not all of our friends have been invited, but lots of people are coming.
- Lots of people are coming, but not all of our friends have been invited.
The exception is for and so which connect a cause/reason to a result. We cannot switch the order of the items being connected because it wouldn't make sense.
- James won’t be at the party for he wasn’t invited.
- for connects a result to a reason
- James wasn’t invited so he won’t be at the party.
- so connects a reason to a result
Punctuation in coordinating clauses
When the two clauses have different subjects, it’s common to separate them with a comma.
- You can take the bus to Old Street, or I can pick you up.
- two different subjects (you and I)
When the two clauses have the same subject or the subject is omitted, the comma is optional.
- You can take the bus to Old Street(,) or (you can take) the train to Market Square.
- same subject/subject omitted
See punctuation for more information.
Inverted Word Order
The coordinating conjunction nor, must follow a negated clause. The subject and auxiliary verb in the nor-clause are inverted.
- We did not buy Jane flowers, nor did we buy her a birthday present.
We did not buy Jane flowers, nor we did buy her a birthday present.
Correlative conjunctions are two-word conjunctions. They are similar to coordinating conjunctions because they link two items of the same grammatical structure. Some typical examples include: either … or, neither … nor, both … and.
- To get to Jane’s you can either take the bus to Old Street or I can pick you up.
- Both Michael and Julia arrived late to the party.
List of Correlative Conjunctions
Correlative conjunctions can be divided into categories based on their meaning or function in a sentence: addition, alternative, cause/reason/result, contrast/comparison or time. The table below provides an overview.
|addition||both … and||Both Michael and Julia arrived late.|
|not only … but also||Jane received not only flowers but also chocolates.|
|alternative||neither … nor||Neither Michael nor Julia arrived at the party on time.|
|either … or||To get to Jane’s you can either take the bus to Old Street or I will pick you up.|
|whether … or||Whether we buy flowers or (we buy) chocolates, it’s the thought that counts.|
|reason/result||such … that||We had such fun dancing that we stayed until 5 am.|
|as … as||The party was as fun as last year.|
|rather … than||I would rather stay here dancing than go home and go to sleep.|
|time||scarcely … when||The music had scarcely begun to play when everyone started dancing.|
|no sooner … than||No sooner had the music started than everyone began to dance.|
Inverted Word Order with Correlative Conjunctions
- When a sentence begins with the correlative conjunctions no sooner … than, not only … but also or scarcely … when, the subject and auxiliary verb are inverted.
- No sooner had the music begun than everybody started dancing.
- Not only did Jane receive flowers but also chocolate.
- Scarcely had the music begun when people started dancing.
- When the sentence begins with a subject the word order is not inverted.
- Jane received not only flowers but also chocolate.
Subordinating conjunctions create a connection between a main or independent clause and a subordinate or dependent clause. We use them to emphasise or support the idea expressed in the main clause. Some common subordinating conjunctions are because, although and when.
- Although the party was very fun, we decided to go home early.
- When the party was over, there was lots of cleaning up to do.
- Everyone danced because the music was so great.
Don’t use two different subordinating conjunctions to connect two clauses in a single sentence. One conjunction is generally enough.
- Because the party was very fun, we stayed until 5 am.
- The party was very fun, so we stayed until 5 am.
- But not:
Because the party was very fun, so we stayed until 5 am.

Word Order with Subordinating Conjunctions
A subordinating conjunction always introduces a dependent, also subordinate, clause i.e. it begins that clause. However, the order of the main and dependent clause is not fixed:
- A dependent clause can usually come first or second in a sentence.
- We arrived late at the party because the traffic was so bad.
- main clause + conjunction + dependent clause
- Because the traffic was so bad, we arrived late at the party.
- conjunction + dependent clause, + main clause
- When the dependent clause goes first, the clauses are separated by a comma.
- Since the music was so great, we danced until 5 am.
- Dependent clause that begin with as or since often come in the first position.
- Since the music was so great, we danced all night long.
- Dependent clauses that show purpose (so, so that, in order that etc.) often come in the second position. Putting them first is more formal.
- She sent the invitations out early, so that everyone would be able to come.
- common order in everyday English
- So that everyone would be able to come, she sent the invitations out early.
- formal style
- The conjunctions so as to and in order to are followed by an infinitive of purpose. In this case, the conjunction can also be left out.
- Jane threw a party (so as) to celebrate her birthday.
- Dependent clauses that begin with until usually come in the second position.
- We danced until Jane turned the music off.
- Before and after are often followed by a participle clause.
- After having danced all night, the guests were exhausted.
- Before leaving the party, everyone sang happy birthday and ate a slice of cake.
