A well-structured paragraph focuses on one main point and follows a simple pattern: introduce and explain the point, provide evidence, analyse it, and link back to the question.

Essential guidance

 

Using a model

You may have encountered models such as MEAL (Main point, Evidence, Analysis, Link), TEAL (Topic sentence, Evidence, Analysis, Link), or PEEL (Point, Evidence, Explanation, Link) at school or from your lecturers. Although the acronyms differ, they all follow the same logic as the structure described in this guidance.

This organises your ideas and makes your writing easy to read. Not every paragraph needs all four parts, but most contain at least the first three.

 

 

Building a paragraph

  • 1. Introduce and explain

    The opening of a paragraph generally has two parts: a topic sentence and an explanation.

    The topic sentence introduces the main idea of that paragraph.

    The explanation gives the reader enough context to understand this main idea before evidence is introduced. This might mean defining a key term (which might require citing a source), giving some background, or showing why the point matters.

    Skipping either part can make a paragraph harder to follow for the reader.

  • 2. Provide evidence

    Evidence supports the point with material from sources. Choose evidence that supports the point in your topic sentence. The type of evidence you use will depend on your discipline. It may include research findings, data, quotations, case examples, theories, or observations.

  • 3. Analyse

    Analysis connects the evidence to your point. Show why the evidence matters and how it supports your topic sentence. Don't leave the reader to make that connection alone. Ask yourself: So what? What does this evidence show about the point I am making?

    Without analysis, evidence feels disconnected or descriptive.

  • 4. Link back to the question

    A linking sentence connects the paragraph back to the assignment question and shows how your point fits your overall response. 

Assignment question

'What factors affect the ability of students to study effectively?'

 

Example

A poor diet can reduce a student's ability to concentrate during the working day.1 Concentration is the ability to focus thought on a specific task (APA, 2018). It depends partly on stable blood sugar levels, which are affected by whether and when a person eats.2 Smith (2020) found that participants who had fasted showed lower alertness and poorer recall of information than those who had eaten breakfast cereal.3 This suggests that skipping meals may reduce a student's ability to retain information, making eating habits directly relevant to academic performance.4 Diet is therefore one factor that can affect how well a student studies, alongside others such as sleep and workload.5

Common issues and how to avoid them

  • Overloaded paragraphs 

    Trying to cover multiple points makes paragraphs confusing. If a paragraph feels too long or contains more than one main idea, split it. For help with making connections between paragraphs clear, go to the signposting guidance.

  • Paragraphs without evidence 

    Points without literature supporting them weaken your writing. Include at least one piece of evidence or example.

  • Paragraphs that don’t link back to the question 

    Check that your point answers the assignment directly. If it doesn’t, revise the paragraph or remove it.

  • Paragraphs that list rather than explain 

    Always explain what your evidence means and why it matters. Don't list evidence without commentary.

 

 

Checklist for a clear paragraph

  • Does it have one main point?
  • Is the topic sentence clear and relevant?
  • Have you explained the point?
  • Does the evidence support the point?
  • Have you analysed the evidence?
  • Does it link back to the assignment question?

 

 

Advanced guidance

The essential guidance offers a clear structure to work from. At an advanced level, that structure is still a useful foundation, but good writing also means knowing when to adapt or move beyond it.

These sections explore how the purpose and function of each part of a paragraph can change with more challenging writing tasks.

 

Stronger topic sentences

A strong topic sentence does more than state a point. It signals your position and shows the reader where the paragraph is going. Your position is the overall informed opinion your argument supports. This is explained in more detail in Points, arguments, and positions.

 

Advanced topic sentences often:

  • state a clear position on the topic
  • show the direction the paragraph will take
  • connect explicitly to the assignment question
  • introduce a contrast, a development, or an important question
  • show how the paragraph fits your overall argument

 

 

Selecting and analysing evidence

Be selective with evidence. Choose the strongest material available rather than everything that seems relevant. Reference all evidence accurately. Do not present evidence without explaining what it shows and how it supports your point.

When selecting evidence, consider:

  • whether it is the strongest available support for your point
  • whether it directly supports, complicates, or qualifies your point
  • what counts as valid evidence in your discipline: consider the sources your lecturers use in teaching and the texts prioritised on your reading list, as these will indicate what your discipline values as evidence

 

Analysis should go beyond explaining what the evidence means. Ask harder questions. Not just what the evidence shows, but how reliable it is, what it assumes, and how it compares with other sources.

This may involve:

  • comparing sources to identify patterns, recurring findings, or conflicting results
  • identifying implications — what the evidence suggests beyond its immediate findings
  • evaluating the strength and limitations of evidence, including what it does not show or where it may be unreliable
  • identifying assumptions or underlying issues
  • showing how the evidence supports your overall argument

 

 

Linking to your argument

A strong paragraph signals clearly how its point contributes to answering your assignment question. In some assignments, such as dissertations or major projects, this is a question you will have set for yourself.

Signalling this connection may involve:

  • explicitly referring to the key terms or concepts in your assignment or argument
  • connecting the analysis to your overall argument
  • showing how the paragraph progresses your overall argument

 

In longer work such as dissertations and major projects, not every paragraph will link directly back to the overall research question. Paragraphs within a section may link to the local point or argument of that section, which in turn serves the broader question.

 

 

Creating flow between paragraphs

Well-connected paragraphs help the reader follow your argument more easily. Linking strategies that help with this include:

  • using a keyword or idea from the previous paragraph
  • using contrast or continuation phrases – to go our signposting guidance for examples
  • showing how the new point develops, deepens, or challenges the previous one
  • ensuring paragraphs appear in a logical sequence

 

 

When paragraphs do more than one job

In practice, a single paragraph often needs to combine more than one of the elements above. A single paragraph might:

  • define or contextualise a concept
  • present evidence
  • analyse the evidence
  • compare it with other sources
  • show limitations
  • link back to the question

 

 

Common issues

  • Unclear links to the overall position

    A paragraph can be well written but still not clearly connect to your argument. Use linking sentences to maintain focus.

  • Repeating earlier points

    Don't reintroduce ideas already covered unless you are adding new insight or depth.

  • Weak topic sentences

    A vague or broad topic sentence will weaken the paragraph from the start. Make sure it signals a specific point and connects to your overall argument.

 

 

Advanced checklist

In addition to the essential checklist above, consider the following:

  • Does the paragraph's topic sentence signal a specific point?
  • Does the topic sentence connect clearly to the assignment?
  • Have you selected the strongest available evidence?
  • Have you analysed the evidence rather than just reporting it?
  • Have you evaluated the reliability or limitations of the evidence?
  • Does the paragraph connect clearly to your overall argument?
  • Does it connect clearly to the paragraphs around it?
  • Have you avoided repeating points already made?
