All Of The Conjunctions | Clear Rules For Learners

If you want your English to flow, you need a good solid grip on conjunctions. These small words link ideas, keep sentences tight, and guide your reader from one point to the next. This guide walks through the main types, shows how they work, and gives you patterns you can copy in your own writing.

Why Conjunctions Matter In English Sentences

A sentence without conjunctions can feel short and flat. You can say one thing at a time, but you cannot show cause, contrast, time order, or choice very well. Once you add the right little linker, your meaning becomes richer and your sentences join together with less effort.

Conjunctions help you:

• join words, phrases, and clauses that belong together
• show how ideas relate, such as cause, time, contrast, and result
• avoid repeating the same nouns and verbs in new sentences
• control the rhythm of your writing with longer, more varied lines

In short, if you understand all of the conjunctions you use every day, you can choose them on purpose instead of by habit.

All Of The Conjunctions In English Grammar

In grammar, a conjunction is a word that links other words, phrases, or clauses. Many guides group all of the conjunctions into three main families: coordinating, subordinating, and correlative. Some teachers also talk about conjunctive adverbs, which act a little like conjunctions at the start of a clause.

Type	Typical Words	Usual Job
Coordinating	and, but, or, so, for, nor, yet	Join equal parts, such as two nouns or two main clauses
Subordinating (time)	when, while, before, after, until, once	Link an action to a point in time
Subordinating (reason)	because, since, as, now that	Show reason and result between clauses
Subordinating (condition)	if, unless, provided that, in case	Set a condition for another action
Subordinating (contrast)	whereas, while, even if	Link ideas that pull in different directions
Correlative	either…or, both…and, not only…but also	Pair up two parts to show balance or contrast
Conjunctive adverbs	meanwhile, instead, then, besides	Connect two sentences or clauses and show the link

This table gives you the big picture. A more detailed breakdown, like the Cambridge Dictionary grammar page on conjunctions, shows many more items in each group, but the main pattern stays the same.

Coordinating Conjunctions

Coordinating conjunctions join parts that have equal weight in the sentence. A classic way to remember them is with the term FANBOYS: for, and, nor, but, or, yet, so. Each one has a typical use.

• and adds one thing to another: “She bought apples and oranges.”
• but shows contrast: “He worked hard, but he was tired.”
• or gives a choice: “Do you want tea or coffee?”
• nor adds a negative choice: “He never calls, nor does he write.”
• for gives a reason: “We stayed inside, for it was cold.”
• yet introduces a surprising twist: “The task looked easy, yet it took hours.”
• so shows result: “It rained, so we stayed home.”

With these short words you can connect whole clauses. Just place the conjunction between the clauses and add a comma before it when each side could stand alone as a full sentence.

Can You Start A Sentence With A Conjunction?

Many learners hear that starting a sentence with and or but is wrong. Modern style guides accept it in both speech and writing, as long as you do not overuse it. The important point is that the clause still links to the idea before it.

Try writing a short paragraph, then breaking one long sentence into two. Begin the second sentence with and, but, or so, and read the pair out loud. If the link still feels clear and the tone suits your topic, the pattern works.

Subordinating Conjunctions

Subordinating conjunctions link a main clause and a dependent clause. The dependent clause cannot stand on its own, because it depends on the rest of the sentence for full meaning.

Here are some common groups of subordinating conjunctions by meaning:

Time Words

Time conjunctions such as when, while, before, after, until, once, and as soon as connect an action to a moment or period. They answer questions like “When did this happen?”

• “She called me when she arrived.”
• “Wait here until I come back.”
• “We will start after everyone sits down.”

Reason And Result Words

Words such as because, since, as, and now that show a cause for something. One clause holds the reason, and the other shows what came from that reason.

• “We stayed home because the weather was bad.”
• “Since you finished early, you can leave.”
• “Now that the test is over, we can relax.”

Condition Words

If, unless, provided that, in case, and similar words set up a condition. The result in the main clause depends on whether the condition happens.

• “If it rains, we will cancel the trip.”
• “You can come, provided that you finish your work.”
• “Take an umbrella in case it rains.”

Contrast Words

Words such as whereas, while, and even if show that two ideas do not match. They can present two people, things, or situations that differ.

• “She loves city life, whereas he prefers the countryside.”
• “While he studied, his friends went out.”
• “Even if it is hard, you should try.”

Many teachers group subordinating conjunctions by meaning in this way. A clear guide such as the Grammarly explanation of conjunctions can give you more lists and extra sentence models.

Correlative Conjunctions And Paired Links

Correlative conjunctions come in pairs. Each half sits near the word or phrase it links, and together they show balance between the two parts. You can think of them as double connectors.

• either…or: “You can either stay here or come with us.”
• neither…nor: “They wanted neither tea nor coffee.”
• both…and: “The room is both bright and quiet.”
• not only…but also: “She is not only kind but also brave.”
• whether…or: “I will help you whether you pass or fail.”

Watch the balance on each side of the pair. If one side links a noun phrase, the other side should also link a noun phrase. If one side links a clause, the other side should match it with a clause. This balance keeps your sentence clear and easy to read.

Conjunctive Adverbs And Sentence Links

Some words do not count as conjunctions in strict grammar, but they work like links between sentences. These include words such as meanwhile, instead, then, and besides. Many style guides call them conjunctive adverbs.

They often appear at the start of a clause after a full stop or semicolon:

• “The first plan failed; instead, we tried a new one.”
• “She studied hard; for this reason, she passed the exam.”
• “He wanted to go out. Meanwhile, the rain grew stronger.”

In speech, these words are common at the start of a sentence. In writing, you often need a comma after them to mark the pause.

Common Mistakes With Conjunctions

Conjunctions feel natural in speech, so many learners do not notice errors when they write. This section shows some frequent problems and better choices.

Problem Sentence	Better Version	Short Tip
“I went to the shop, I bought bread.”	“I went to the shop, and I bought bread.”	Add a conjunction or split into two sentences.
“She is smart but also she is lazy.”	“She is smart, but she is lazy.”	Use a single conjunction for contrast.
“Though it was late, but we stayed out.”	“Though it was late, we stayed out.”	Do not double up contrast words.
“Because he was tired, so he slept early.”	“Because he was tired, he slept early.”	Use either a reason word or so, not both.
“Either you can call me, and you can send an email.”	“You can either call me or send an email.”	Place each half of the pair before what it links.
“He did not study, for this reason he passed.”	“He did not study; for this reason, he failed.”	Match the meaning of the connector with the result.
“He was angry, because they were late.”	“He was angry because they were late.”	Drop the comma in short clauses with because.

Many of these mistakes come from translation. In some languages you can stack two conjunctions in a row or repeat them, but English usually needs just one clear link between clauses.

Practice Steps To Use Conjunctions Well

Reading and writing with attention is the best way to build control over conjunctions. Here are some simple steps you can follow this week.

Step 1: Spot Conjunctions In What You Read

Take a short news article or blog post. Underline every conjunction you find, along with a few conjunctive adverbs. Mark what each one does: add, contrast, give a reason, show time, or set a condition. Over time, you will start to see patterns.

Step 2: Write Short Sentences, Then Join Them

Write five simple sentences about your day, with no conjunctions. Then rewrite them as longer sentences by joining related ideas. Try one version with coordinating conjunctions and another with subordinating ones. This small exercise gives you quick practice with all of the conjunctions you use most often.

Step 3: Try New Conjunctions In Safe Practice

Pick two or three words from each group in the first table that you do not use much. Write your own sentences with them. If you link them to actions from your own life, you will remember them more easily than if you just read lists.

Step 4: Check Sentence Balance

When you use correlative pairs such as either…or and both…and, read the sentence aloud and listen for balance. If the two halves feel uneven, rewrite them so that the grammar on each side matches. This habit will keep your writing clean.

Step 5: Edit Old Writing For Connectors

Take an old paragraph from your homework, a social media post, or an email you sent. Rewrite it once with few conjunctions so that the sentences are short and plain. Then write a second version that joins related ideas with different kinds of conjunctions.

Compare the three versions. The first may sound sharp but rough, the second may sound flat, and the third often feels smoother and more natural. This simple check shows you how much power these small linking words have in real communication.

Bringing It All Together

Conjunctions might look small, but they shape every paragraph you write. Once you know the three main families and how they work, you can link ideas in clear ways that guide your reader through your thoughts. Keep this guide close, practice a little each day, and soon choosing the right connector will feel natural whenever you speak or write.
