Welcome to Expository Writing. Building on the foundation you laid in Functional English, this module will elevate your ability to understand what expository writing truly is.

1- Understanding Expository Writing

1.1- Definition

The word ‘Expository’ has been taken from Latin word ‘Exponere’ which means ‘to reveal something or to bring something forward’. Hence, expository writing produces such texts which are essentially real, fact-based and authentic. Unlike a fictional story, it aims to define a term, explain a scientific concept, describe a process, inform how a process works, or clarify complex ideas by presenting objective information.

1.2- Purpose and Application

Expository writing is a form of informational writing whose primary function is to educate the reader (not to entertain) by presenting original information. Its key applications find expression in:

Textbooks: Explaining concepts in science, history and mathematics

Academic Writing: Lab reports, book reviews and research papers

Business: Reports, memos and instructional manuals

Everyday Life: Recipes and even this chapter

1.3- Types of Expository Writing

Since expository writing focuses on facts, authenticity of knowledge and logical sequence of information, it may be broken down into different types based on their purpose and function.

1.3.1- Description

This type of writing paints a vivid picture of a person, thing or place with words through describing real-time characteristics of the object under discussion.

1.3.2- Illustration

It aims to elaborate an idea or claim by putting examples in support of evidence. For example, one may explain the concept of urban heat by citing temperature differences in figures between Multan and its rural outskirts.

1.3.3- Classification

This type of writing classifies the items into different types or categories in order to facilitate in-depth cognition. For example, the classification of expository writing into its types adds to its overall comprehensibility.

1.3.4- Process Analysis

It helps explain stepwise how something works (an instruction manual) or how to do something (a recipe).

1.3.5- Cause and Effect

It aims to explore why something happened (cause) and what were its consequences (effect); such as describing the causes of climate change in Pakistan and its effects on its agriculture.

2- Characteristics of Effective Expository Writing

For expository writing to achieve effectiveness, it must possess the following three essential characteristics.

2.1-  Clarity

Clarity in writing means using precise language (accurate words), simple language (jargon free) and more direct sentences (active voice). This is the most salient feature of expository writing without which the text loses its main function and purpose. It is all about choosing the right word to convey the exact meaning. For example, instead of saying, ‘All went wrong’, one must write, ‘The inaccurate results were the outcome of faulty calibration’.

2.2- Coherence

Coherence refers to logical flow of ideas to enhance readability. Logical order, transitions and uniformity are the building blocks of coherence.

Logical Order: Arranging ideas in a manner that makes sense (Chronological, cause-effect, most to least important).

Transitions: Using the sentence or paragraph connectors (however, therefore, hence) in order to keep the reader engaged throughout the text.

Uniformity: Ensuring all ideas connect back to central theme.

2.3- Organization

Organization refers to the structural framework of a piece of writing. A well-organized text always has a beginning, middle and end. Particularly, an expository essay follows a five-paragraph structure: an introduction, three body paragraphs and a conclusion (1-3-1). Lack of organization can lose the interest of the reader.

3- Introduction to the Paragraph Writing

Just as a house is built brick by brick, an essay is constructed paragraph by paragraph. The total effectiveness of an expository writing primarily depends on the efficacy of its paragraphs.

3.1- What is a Paragraph

A collection of sentences following a logical sequence with an aim to describe a particular theme is known as a paragraph. In expository writing, a standard paragraph has three key parts.

3.1.1- The Topic Sentence

This is the first sentence of the paragraph. It is written in line with the title of the expository writing. It tells the reader what the paragraph is about. Strong topic sentences avoid too general statements and are constructed in a way that they necessarily provoke thought to explore more.

Poor: There are many reasons for climate change.

Effective: Deforestation and burning of crude oil are the main drivers of climate change which accelerate greenhouse effect.

3.1.2- Supporting Evidence

These sentences immediately follow up the topic sentence. They may be three or more in number which tend to provide evidence, via illustrations or explanation, in support of the claims broached in the topic sentence. Illustrations and explanations may include examples, facts, statistics or interpretations.

Fact: According to the United Nations, over 68% of total greenhouse emissions and nearly 90% of all carbon dioxide emissions come from burning of fossil oils which collectively contribute to overall climate change resulting in global warming.

Statistic: Deforestation has a major role in the drama of climate change inasmuch as about 11% of greenhouse gas emission comes from rapid tree cutting and burning of forests; Food and Agriculture Organization (FAO) reports.

Interpretation: Trees in forests continuously absorb carbon dioxide from the atmosphere and when they are destroyed, they not only stop acting as ‘Carbon Sink’ but also start releasing carbon dioxide already stored within them and thus exacerbate global warming which affects our climate adversely.

3.1.3- Concluding Sentence

Finally, the whole discussion of the paragraph is summarized in a single sentence. If next paragraph follows, it provides a transition to the upcoming paragraph.

Concluding line: In short, a full stop to deforestation and crude oil consumption can end up clime change and stabilize the global temperature at constant 18 °C.

Transition line: As a result of these harmful emissions, our plant is experiencing rapid change in its friendly ecosystem and moderate weather patterns. (It will open a discussion on ‘ecosystem and weather patterns’ in the next paragraph)
