How to Comment on a Text · Step 3

The Language Building Blocks

Learn how to build sentences that do real argumentative work — and develop a language toolbox you can actually use in your paragraphs.

Step 3

Learn what a strong sentence actually does

In Step 1 and Step 2, you learned how a paragraph is built. In this step, you now focus more closely on the language inside that paragraph: how sentences connect ideas, explain meaning and guide the reader from one thought to the next.

What this trains

Strong writing does not only depend on good ideas. It also depends on whether each sentence actually does something useful inside the paragraph.

This step helps you understand sentence function and build a practical toolbox of phrases for different moments in your argument.

You are not just writing sentences — you are guiding thought

Many weak paragraphs are not weak because the writer has no ideas. They are weak because the language does too little.

A sentence can name an idea, but it can also explain it, sharpen it, connect it to the previous sentence or show why it matters.

In strong comments, sentences do not simply sit next to each other. They work together and move the argument forward.

What a strong sentence actually does

Strong writing is not about sounding complicated. It is about doing more work in each sentence.

1. A weak sentence only names something

The text shows a problem.

This sentence is not wrong. But it does very little for the reader. It does not say what the problem is, how the text presents it or why it matters.

2. A better sentence adds precision

The text shows the pressure young people experience on social media.

Now the reader understands more clearly what the issue is. But the sentence still mostly names the idea. It still does not explain the meaning behind it.

3. A strong sentence explains and guides

The text highlights the pressure young people experience on social media, which suggests that online platforms strongly influence self-image.

This sentence now does real argumentative work. It not only names the issue, but also interprets it and guides the reader towards a clearer understanding.

  • it identifies the issue more precisely
  • it explains what the text suggests
  • it helps the reader follow the argument

The key principle

Strong sentences do not just state ideas. They develop them.

How a sentence grows

Better writing often does not begin with a completely new sentence. It begins by making your sentence more precise, more meaningful and more useful.

Step 1

The text criticises social media.

Step 2

The text criticises the pressure created by social media.

Step 3

The text criticises the pressure created by social media, especially on young users.

Step 4

The text criticises the pressure created by social media, especially on young users, which suggests that online platforms shape identity.

Step 5

The text criticises the pressure created by social media, especially on young users, which suggests that online platforms play a central role in shaping identity and self-perception.

What to notice

The sentence improves because each version does a little more. It becomes more precise, then more specific, then more interpretive. That is how stronger academic writing usually develops.

Your language toolbox

Do not learn phrases randomly. Learn them for the moment in which you need them.

When you want to explain meaning

You already have a point or an example — now you need to show what it means.

  • This shows that …
  • This suggests that …
  • This indicates that …
  • This helps to explain why …
  • This makes it clear that …
  • What becomes visible here is …

Use these when you move from evidence to interpretation.

When you want to connect ideas

You want the paragraph to feel connected instead of fragmented.

  • As a result, …
  • For this reason, …
  • Therefore, …
  • In this way, …
  • This leads to the conclusion that …
  • From this perspective, …

Use these when one thought grows logically out of the previous one.

When you want to sharpen your point

You want your sentence to sound more precise and more focused.

  • A key issue here is …
  • What matters most is …
  • At the centre of this argument is …
  • The text particularly highlights …
  • The most striking aspect is …
  • One important reason is …

Use these when you introduce or refine the point you want to develop.

When you want to add nuance

You want your writing to sound more controlled and less simplistic.

  • However, …
  • At the same time, …
  • To some extent, …
  • While this is true, …
  • Even so, …
  • At least in part, …

Use these when you want to qualify a point instead of sounding too absolute.

The most important habit

Do not ask: Which phrase sounds advanced? Ask: What does my sentence need to do at this moment?

Review before you move on

Use this check to see whether your sentences are beginning to do more than simply state ideas.

Ask yourself

  • Does this sentence only name an idea, or does it also explain it?
  • Does it help the reader see why the point matters?
  • Does it connect naturally to the sentence before?
  • Could I make the wording more precise?
  • Would a phrase from my toolbox improve the sentence function?

Move on to Step 4

In the next step, you go one level further: you learn how strong your claims should sound and how to use hedging so that your writing becomes more balanced and intellectually credible.
