A conjunction is a word that connects words, phrases, or clauses within a sentence. It gives structure to language by linking ideas smoothly so that communication becomes clear and connected. Without conjunctions, writing and speaking would sound broken or incomplete.
In this lesson, you will study the definition, rules, and types of conjunctions. You will also see examples, common mistakes, and practice exercises to master this important grammar topic.
What is a Conjunction?
A conjunction is a word that joins words, phrases, or clauses to form a connected sentence. It prevents ideas from being broken into short parts and allows smooth communication. In grammar, conjunctions act as links between thoughts, giving structure and balance to a sentence.
Functions of Conjunctions in Sentences
Conjunctions serve different roles depending on the relationship they show:
Addition: Join similar ideas. She likes tea and coffee.
Contrast: Show opposition. He is rich, but unhappy.
Cause and Effect: Link reasons and results. She was late, so she missed the bus.
Choice: Offer alternatives. You may come today or tomorrow.
Condition or Time: Mark situations. We waited inside until the rain stopped. Did you know? Conjunctions are one of the oldest recorded parts of speech in English, appearing in texts since Old English.

Conjunction Rules
Balance similar parts: Conjunctions join like units.
She bought bread and butter.
Avoid double conjunctions: One link is enough.
❌ He left because since he was tired. → ✅ He left because he was tired.
Correct pair use: Correlatives must balance.
She is not only smart but also kind.
Subordinating placement: Place before the dependent clause.
I will wait until she arrives.
Comma with coordinating conjunctions: Use commas when joining two clauses.
I was tired, but I continued working.
Do not join unlike parts: Match grammatical units.
❌ She is tall and honesty. → ✅ She is tall and honest.
Conjunctions and emphasis: A conjunction may start a sentence for effect.
“But I still believe in you.”
Types of Conjunction
Coordinating Conjunctions
These connect equal parts such as nouns, clauses, or phrases. The seven coordinating conjunctions are remembered as FANBOYS.
I wanted to call, but he was asleep.
She sings well, and she dances beautifully.
You may stay here, or you may leave.
It rained, yet we continued playing.
Subordinating Conjunctions
Subordinating conjunctions join a dependent clause with an independent clause, showing cause, time, or condition.
They will play whether it rains or shines. Did you know? The phrase “either…or” has been in use since the 14th century.
Use of Conjunction
Conjunctions help extend sentences, reduce repetition, and add clarity. They show relationships such as choice, cause, contrast, or sequence. For example: “He studied well, so he passed his exam.” The word so links cause with result.

Common Mistakes with Conjunctions
❌ Although it was raining, but we went outside. ✅ Although it was raining, we went outside. (Do not use two conjunctions for one idea.)
❌ He will either sing or he will dance. ✅ He will either sing or dance. (The correlative pair must be balanced.)
❌ I don’t know neither him nor his friend. ✅ I know neither him nor his friend. (Avoid double negatives.)
Conjunctions vs Relative Pronouns
A conjunction links clauses, while a relative pronoun introduces a clause that describes a noun.
Conjunction: She stayed home because she was sick.
Relative pronoun: The student who answered first received praise.
Exceptions and Special Cases
Some words act as both conjunctions and other parts of speech, e.g., for as preposition or conjunction.
Modern English accepts sentence beginnings with conjunctions for style, though traditional grammar once discouraged it.
Certain correlative pairs are flexible in informal use, e.g., “both…as well as” though “both…and” is standard.
