Introduction, Body and Conclusion
A CSS essay has three structural movements: an introduction that earns the reader's trust, a body that delivers on the introduction's promise, and a conclusion that consolidates the argument without rehashing it. Each obeys its own grammar of expectation.
The introduction (150–250 words)
The introduction has three jobs, in this order:
- Frame the issue in a way that signals you understand its scope and stakes.
- State the thesis — your one-sentence position on the question.
- Preview the structure — a brief sentence indicating the route the essay will take.
A weak opening recycles the topic in inflated language: "Energy is the lifeblood of every nation, and Pakistan, being a developing country, is suffering from acute shortage of energy since long." This sentence says nothing the examiner does not already know.
A stronger opening positions a tension or paradox:
Pakistan today possesses more installed electricity-generation capacity than at any point in its history — and yet, in the summer of 2024, urban centres faced eight to twelve hours of load-shedding while rural areas endured even longer. The paradox is not one of generation but of governance: the country produces enough electrons; it cannot move, price or pay for them.
This opening earns the next paragraph. It establishes a specific puzzle, names the period and scale, and forecasts a thesis without rushing to declare it.
- Start with a specific fact, paradox, or scene — not with a definition or a proverb.
- Avoid clichés: "Since time immemorial", "It is a matter of fact that", "The need of the hour is…".
- Include at least one date or number in the introduction itself.
- End with a thesis sentence that takes a clear position.
- Do not exceed roughly 10–12% of total essay length.
The body (75–80% of length)
Each body paragraph should function as a mini-essay with its own internal structure:
A reliable structure for body paragraphs:
- P — Point: a topic sentence stating the paragraph's claim.
- E — Evidence: a fact, date, statistic, named example, or quotation.
- E — Explanation: how the evidence supports the point.
- L — Link: a transition that prepares the next paragraph.
A 200-to-300-word paragraph that completes all four moves is almost always stronger than a 500-word paragraph that does only one or two.
A worked example, on the energy crisis topic:
The transmission and distribution network, not generation, is the bottleneck. Even when generation plants are running at capacity, the National Transmission and Despatch Company (NTDC) is unable to evacuate power efficiently from southern coal-fired plants to northern demand centres; transmission losses average 2.8%, and DISCO-level losses range from 9% in IESCO to over 30% in SEPCO and QESCO. The result is the perverse phenomenon of "grid-bottling": generation idle in the south while feeders in the north are load-shed. Fixing the transmission backbone is therefore prior, both logically and financially, to building any new generation capacity — a sequencing the 2024 Indicative Generation Capacity Expansion Plan finally acknowledges.
Note the structure: a clear claim, a specific evidence cluster, an interpretive sentence ("grid-bottling"), and a forward-pointing link to policy.
Transitions
Body paragraphs must be stitched to one another. Aimless paragraph breaks erode coherence. Useful transition signals include:
| Function | Phrases |
|---|---|
| Adding | "A second, related, structural problem is…", "Equally consequential is…" |
| Contrasting | "The picture is, however, less straightforward when one considers…", "A counter-current runs through this argument:" |
| Causing | "This pattern is not accidental. It follows directly from…" |
| Sequencing | "At the level of policy, by contrast, the failures are more recent.", "If the diagnosis is structural, the remedies must be institutional." |
Avoid the lazy quartet "Firstly, Secondly, Thirdly, Lastly". Examiners read it as the absence of thought.
The conclusion (150–250 words)
A good conclusion does three things:
- Restates the thesis in fresh language (not the same sentence as the introduction).
- Synthesises the body — pulls the main lines of argument together into a single judgement.
- Looks forward — points to a stake, a risk, or a recommendation without introducing wholly new evidence.
A weak conclusion summarises ("In this essay, I have argued that…"). A strong conclusion consolidates:
The crisis Pakistan calls "energy" is in truth a crisis of incentives. So long as DISCOs are shielded from competition, theft is unpriced, and capacity payments reward unbuilt megawatts, no expansion of generation will keep ahead of demand. The reforms are unglamorous — metering, tariffs, governance boards, accelerated retirement of imported-fuel plants. But the alternative is a slow drift in which the country pays ever-larger sums for ever-less-reliable power. The lights, in the end, will stay on only when the institutions behind them do.
Never introduce a new statistic or argument in the conclusion. If a point is important enough to mention, it belongs in the body. The conclusion is for judgement, not data.
Proportion check
A rough internal balance for a 3,000-word essay:
| Section | Words | Proportion |
|---|---|---|
| Introduction | 200–250 | ~8% |
| Body (5 paragraphs × ~500) | 2,400–2,600 | ~83% |
| Conclusion | 200–250 | ~8% |
| Outline (separate page) | 200–300 | — |
If your introduction runs to 500 words or your conclusion to 80, the proportions themselves will register as off-balance to a reader scanning the script.
