Why Do We Need Linking Words?
Have you ever tried to tell a friend why something is your favorite, but your sentences sounded choppy? Maybe you said, "I love pizza. It tastes good. The cheese is melty." Those sentences are fine on their own, but they feel like separate puzzle pieces that haven't been snapped together yet. Linking words are the special snap-pieces that connect your ideas so your writing flows smoothly.
People have been connecting their ideas with linking words for a very, very long time. Let's take a quick peek at how this idea grew!
Here is the big question this lesson answers: How can you use linking words and phrases to connect your opinion to your reasons so your writing makes sense and sounds great? Let's find out!
The Key Linking Words You Need to Know
A linking word (sometimes called a connecting word) is a word or short phrase that joins two ideas together. In opinion writing, you have an opinion (what you think) and reasons (why you think it). Linking words are the glue between them!
Because
Therefore
Since
For Example
Also & Another Reason
See It! The Opinion–Reason Bridge
Look at the picture below. On the left side is your opinion — what you believe. On the right side is your reason — why you believe it. In the middle is the linking word that connects them like a bridge.
See how the word because works like a bridge? Without it, you'd have two short sentences: "I think dogs are the best pets." and "They are loyal and friendly." That's okay, but when you connect them with because, the reader understands exactly why you feel that way. Your writing sounds stronger and clearer!
How Linking Words Work in Your Writing
Each linking word has a special job. Let's look at the three main jobs linking words do in opinion writing.
Notice something cool? You can put your opinion first and then add a reason with because. Or you can flip it around! You can put the reason first using since, and then share your opinion. Both ways work. Here's a quick look:
Both sentences say the same thing! You just switched the order. Using different linking words and different orders makes your writing more interesting to read.
Your Linking Words Guide
Here is a handy chart that shows each linking word, what it does, and an example. You can come back to this chart whenever you're writing!
| Linking Word | What It Does | Example Sentence |
|---|---|---|
| because | Gives a reason (answers "why?") | Reading is fun because you can visit imaginary worlds. |
| since | Gives a reason (often starts the sentence) | Since it's cold outside, I think we should wear jackets. |
| therefore | Shows a result or conclusion | Vegetables help us grow. Therefore, we should eat them every day. |
| for example | Adds a specific detail or proof | Animals help people. For example, dogs guide people who can't see. |
| also | Adds another reason | Parks are great for running. Also, they have swings and slides. |
| another reason | Adds one more reason | Another reason I like art class is that we get to use bright colors. |
Use this flowchart whenever you're writing and can't decide which linking word fits. Ask yourself: Am I telling why? Use because or since. Am I showing a conclusion? Use therefore. Am I giving a detail? Use for example. Am I piling on more reasons? Use also or another reason.
Worked Example: Writing an Opinion Paragraph
Let's write a short opinion paragraph together using linking words! Our topic is: "What is the best school subject?"
Look at how smooth that sounds! Every sentence is connected. The reader knows your opinion, your reasons, your details, and your conclusion. That's the power of linking words!
Do's and Don'ts of Linking Words
Linking words are super helpful, but you want to use them well. Here's a chart to help you remember the right way and the not-so-great way to use them.
| ✅ DO THIS | ❌ DON'T DO THIS |
|---|---|
| Use linking words to connect an opinion to a real reason. | Use linking words with no real reason. ("I like cats because I do.") |
| Try different linking words so your writing sounds interesting. | Use the same word every time. ("Because… because… because…") |
| Put a comma after therefore, for example, and also when they start a sentence. | Forget the comma. ("Therefore everyone should try it.") |
| Make sure your reason actually supports your opinion. | Connect ideas that don't go together. ("I like math because it's Tuesday.") |
| Use since at the beginning and because in the middle for variety. | Always put your reason in the same spot. |
Level Up: Where Linking Words Take You Next
Right now, you're learning linking words for opinion writing. But guess what? As you grow as a writer, you'll use connecting words in all kinds of writing! Here's a peek at what's coming:
| What You Learn Now (3rd Grade) | What Comes Next (4th & 5th Grade) |
|---|---|
| Use because, since to give reasons | Use consequently, as a result, due to for stronger connections |
| Use for example to add details | Use for instance, specifically, in particular |
| Use also to add reasons | Use furthermore, in addition, moreover |
| Use therefore to show a conclusion | Use in conclusion, as a result, thus |
| Write opinion paragraphs | Write full opinion essays with introductions and conclusions |
