Using Words, Phrases, and Clauses to Create Cohesion in Arguments - 7th Grade Writing

Section 1

Why Cohesion Matters: A Brief History

Have you ever read a paragraph that felt jumpy—like the writer was leaping from one idea to the next with no warning? That's what happens when writing lacks cohesion (the quality of sentences and ideas sticking together smoothly). People have cared about connecting ideas in writing for thousands of years. Let's look at a few key moments.

~350 BCE • Aristotle's Rhetoric

The ancient Greek philosopher Aristotle taught that a good argument needs three parts: a claim (what you believe), reasons (why you believe it), and evidence (proof). He also stressed that ideas must flow logically from one to the next.

1776 • The Declaration of Independence

Thomas Jefferson used transition words like "therefore," "because," and "when" to connect his claims about freedom to his evidence about the king's unfair actions. This document is a masterclass in cohesion.

1960s • Linguistics Research

Researchers in the field of linguistics (the study of language) began to study exactly how sentences connect to each other. They identified special words and phrases—called cohesive devices—that glue ideas together.

2010 • Common Core Standards

The Common Core State Standards for English Language Arts were created, and they included a specific goal: students should "use words, phrases, and clauses to create cohesion and clarify the relationships among claim(s), reasons, and evidence."

So here's the big question this lesson answers: How do you pick the right words, phrases, and clauses so that your argument reads like a smooth, connected conversation instead of a pile of random sentences?

Section 2

Core Tools for Creating Cohesion

Before we dive in, let's make sure you know three important terms. A claim is the main point or opinion you're arguing. A reason is an explanation of why your claim is true. Evidence is a specific fact, example, or detail that supports your reason. Cohesion is what connects all three so the reader can follow your thinking.

Transition Words

Single words that signal how two ideas relate. Examples: however, therefore, also, because, although, finally. They're like road signs that tell the reader what's coming next.

Transition Phrases

Groups of words that work together to connect ideas. Examples: for example, on the other hand, as a result, in addition to, according to. They give more detail than a single word can.

Transition Clauses

Longer groups of words that have a subject and a verb and link one part of your argument to another. Example: "While some people argue that…" or "Because the data shows that…"

Repeated & Referencing Language

Repeating a key term or using pronouns like this, these, or that to refer back to an earlier idea. This helps the reader stay connected without getting lost.

✦

Key Takeaway

Think of your argument like a chain. Each link is a sentence. Transition words, phrases, and clauses are the metal rings that hook one link to the next. Without those rings, you just have a pile of loose links on the ground—not a strong chain.

Visual Map: How Cohesion Connects an Argument

The diagram below shows how a claim, reasons, and evidence connect through cohesive language. Notice how the green transition words and phrases act as bridges between each part of the argument.

In this diagram, every green label is a transition word or phrase. Without them, the reader would jump from the claim straight to the evidence with no idea how the pieces fit. The transitions tell the reader: "Here comes a reason," "Here comes proof," or "Here's the point of it all."

Section 4

How Cohesive Language Works

Cohesive language does one main job: it shows the relationship between two ideas. There are several kinds of relationships you'll use in argumentative writing. Let's break them down.

ℹ

Cause & Effect

Use these when your reason explains why the claim is true, or when evidence shows the result of something. Words: because, since, therefore, so, consequently, thus Phrases: as a result, for this reason, due to the fact that Clauses: "Because research shows that…" / "Since students need breaks…"

ℹ

Addition

Use these when you are adding another reason or another piece of evidence on top of what you've already said. Words: also, furthermore, moreover, additionally Phrases: in addition, along with this, what is more Clauses: "Not only does exercise help focus, but it also…"

ℹ

Contrast / Counterargument

Use these when you bring up an opposing view and then push back against it. Words: however, although, yet, nevertheless, still Phrases: on the other hand, even though, in contrast Clauses: "While some people argue that recess wastes time…"

ℹ

Example / Evidence Introduction

Use these when you're about to present a specific fact, statistic, or example as proof. Words: specifically, notably Phrases: for example, for instance, according to, as shown by Clauses: "As the data from the 2019 study demonstrates…"

ℹ

Conclusion / Summary

Use these when you're wrapping up and restating your main point. Words: therefore, ultimately, clearly Phrases: in conclusion, for all of these reasons, all in all Clauses: "Given that both research and real experience support this idea…"

Here's the cool part: once you memorize even a handful of these transitions, your writing instantly sounds more organized and mature. You don't need to use fancy vocabulary. You just need to signal the type of connection between your ideas.

Types of Cohesive Devices: A Detailed Breakdown

Let's look at how the same argument paragraph changes when we use different levels of cohesive language. Below is a side-by-side comparison.

Notice how the version on the right isn't longer because of extra ideas. It's smoother because transition words and phrases tell the reader exactly how each sentence relates to the one before it.

Relationship	Example Words & Phrases	When to Use
Cause & Effect	because, so, therefore, as a result	Connecting a reason to a claim
Addition	also, furthermore, in addition, moreover	Adding a second reason or piece of evidence
Contrast	however, although, on the other hand, while	Addressing a counterargument
Example	for example, for instance, according to	Introducing specific evidence
Conclusion	therefore, in conclusion, clearly, ultimately	Wrapping up your argument

Section 6

Worked Example: Building a Cohesive Paragraph

Let's walk through writing an argumentative paragraph step by step, adding cohesive language as we go. Our topic: "Cell phones should not be allowed in classrooms."

Building a Cohesive Paragraph

1
Step 1 — State Your Claim

Start with a clear statement of your position. This is the sentence that everything else will connect to.

Cell phones should not be allowed in classrooms.
2
Step 2 — Introduce Your First Reason with a Cause/Effect Transition

Now connect a reason to your claim. Use a word like "because" or a phrase like "the primary reason is that" so the reader understands why you hold this belief.

Cell phones should not be allowed in classrooms because they distract students from learning.
3
Step 3 — Add Evidence with an Example Transition

Now support your reason with evidence. Use a phrase like "For example" or "According to" to introduce your proof.

Cell phones should not be allowed in classrooms because they distract students from learning. For example, a study by Common Sense Media found that 59% of parents say their teen gets distracted by their phone during homework.
4
Step 4 — Add a Second Reason with an Addition Transition

You have more than one reason, right? Use a transition like "In addition" or "Furthermore" to stack your next reason on top of the first.

… 59% of parents say their teen gets distracted by their phone during homework. Furthermore, phones can be used for cyberbullying during school hours.
5
Step 5 — Address a Counterargument with a Contrast Transition

A strong argument considers the other side. Use a clause like "While some people believe that…" to show you've thought about opposing views.

While some people believe that phones are useful learning tools, the risks of distraction and cyberbullying outweigh the benefits.
6
Step 6 — Conclude with a Summary Transition

Wrap up by restating your claim using a conclusion transition like "For all of these reasons" or "Therefore."

For all of these reasons, cell phones should be kept out of classrooms to help students stay focused and safe.
7
Final Result — The Complete Paragraph

Cell phones should not be allowed in classrooms because they distract students from learning. For example, a study by Common Sense Media found that 59% of parents say their teen gets distracted by their phone during homework. Furthermore, phones can be used for cyberbullying during school hours. While some people believe that phones are useful learning tools, the risks of distraction and cyberbullying outweigh the benefits. For all of these reasons, cell phones should be kept out of classrooms to help students stay focused and safe. Notice how every highlighted word or phrase tells you the relationship between the ideas. The paragraph flows smoothly from claim → reason → evidence → additional reason → counterargument → conclusion.

Strengths, Pitfalls, and Common Mistakes

Using transitions is powerful, but there are some traps to watch out for. Let's compare the strengths of good cohesive writing with some common mistakes students make.

Strength ✓	Common Mistake ✗	How to Fix It
Using the right transition for the relationship	Using "also" when you mean "however" (wrong signal)	Ask: am I adding, contrasting, or causing? Pick accordingly.
Placing transitions at natural connection points	Starting every sentence with "Also" or "Furthermore"	Vary your transitions. Some go at the start, some in the middle of a sentence.
Using transitions to genuinely connect ideas	Using transitions as decoration when the ideas don't actually connect	Make sure your sentences actually relate to each other logically first.
Mixing words, phrases, and clauses for variety	Using only one-word transitions like "also, also, also"	Challenge yourself to use at least one phrase and one clause per paragraph.
Using a conclusion transition to wrap up	Ending abruptly with no concluding signal	Always signal to the reader that you're wrapping up: "Therefore…" or "In conclusion…"

✦

Key Takeaway

Using transitions is like using turn signals while driving. If you signal left but turn right, you'll confuse everyone. If you never signal at all, people won't know where you're going. The key is to signal honestly and clearly—match the transition to the actual relationship between your ideas.

Practice Problems

Try these five problems. They get a little harder as you go. Click "Show Answer" to check your work after you've given each one a try.

Question 1: Problem 1 — Conceptual

What is the main purpose of using transition words, phrases, and clauses in an argument? Choose the best answer. (A) To make your essay longer (B) To show the relationships between your claim, reasons, and evidence (C) To use fancy vocabulary (D) To confuse the reader

Show answer

Answer: (B) — The main purpose of transition words, phrases, and clauses is to show the relationships between your claim, reasons, and evidence. They help the reader understand how your ideas connect—not just what your ideas are. Nice work if you got this one!

Question 2: Problem 2 — Identification

Read the sentence below. Identify the transition word or phrase and explain what type of relationship it shows. "Students should be required to wear uniforms. For instance, schools with uniform policies report 23% fewer disciplinary problems."

Show answer

The transition phrase is "For instance." It shows an example/evidence relationship. The writer is introducing a specific fact (the 23% statistic) to support the claim that uniforms should be required. "For instance" signals to the reader: "Here comes proof of what I just said."

Question 3: Problem 3 — Intermediate

The following paragraph is missing transitions. Fill in each blank with an appropriate transition word, phrase, or clause from the list: Because, Furthermore, For example, While some might say, Therefore. "Students should have homework-free weekends. _______ weekends are meant for rest, students need that time to recharge. _______ a study from Stanford showed that too much homework increases stress. _______ less homework means more family time. _______ weekends without homework are too unstructured, students could use that time for reading or creative projects instead. _______ schools should consider making weekends homework-free."

Show answer

Here's one correct way to fill in the blanks: "Students should have homework-free weekends. Because weekends are meant for rest, students need that time to recharge. For example, a study from Stanford showed that too much homework increases stress. Furthermore, less homework means more family time. While some might say weekends without homework are too unstructured, students could use that time for reading or creative projects instead. Therefore, schools should consider making weekends homework-free. Each transition signals a different relationship: Because = cause/effect, For example = evidence, Furthermore = addition, While some might say = counterargument, and Therefore = conclusion.

Question 4: Problem 4 — Applied

Imagine your school is deciding whether to add a salad bar to the cafeteria. You believe it's a great idea. Write a short paragraph (4–5 sentences) that includes: • A clear claim • At least one reason connected with a cause/effect transition • At least one piece of evidence introduced with an example transition • A concluding sentence with a summary transition

Show answer

Sample answer: "Our school should add a salad bar to the cafeteria because it would encourage students to make healthier choices. According to the USDA, students who eat fruits and vegetables at lunch perform better on afternoon tests. In addition, a salad bar gives students more options, which means less food waste. For these reasons, a salad bar would benefit both student health and our school environment." Your paragraph might look different, and that's okay! The key is that you used transitions to connect your claim → reason → evidence → conclusion. Check that each transition matches the actual relationship between the ideas.

Question 5: Problem 5 — Critical Thinking

Read the paragraph below. It uses transition words, but some of them are wrong—they signal the wrong type of relationship. Find the two incorrect transitions and explain why they don't work. Then suggest better replacements. "Schools should teach financial literacy. However, many adults struggle to manage money, which shows that current education is not enough. Although a survey by Jump$tart found that only 24% of high school seniors could answer basic financial questions correctly. Therefore, adding a financial literacy class would prepare students for real life."

Show answer

Mistake 1: "However" — This word signals contrast (an opposing idea), but the sentence that follows actually supports the claim. It should be a cause/effect or example transition. A better choice: "Because" or "For instance." (Example: "For instance, many adults struggle to manage money…") Mistake 2: "Although" — This word signals contrast, but the sentence is presenting evidence that supports the argument, not an opposing view. A better choice: "In fact," or "Specifically." (Example: "In fact, a survey by Jump$tart found…") Great job if you spotted both! This problem shows why it's so important to pick transitions that match the actual relationship. Using the wrong signal word confuses your reader, even if your ideas are strong.

Summary

Lesson Summary

Summary

In this lesson, you learned that cohesion is the glue that holds an argument together. You explored four main tools for creating cohesion: transition words (single words like because, however, also), transition phrases (groups of words like for example, on the other hand, as a result), transition clauses (word groups with a subject and verb like "While some people argue that…"), and repeated or referencing language that points back to earlier ideas.

You also learned that every transition signals a specific relationship between ideas—whether it's cause and effect, addition, contrast, example/evidence, or conclusion. Choosing the right transition is just as important as using one at all. When you match your transitions to the real relationships between your claim, reasons, and evidence, your writing becomes clearer, smoother, and more convincing. These skills will serve you in every essay, report, and argument you write—from now through college and beyond.
