Explanatory texts play an important role in both academic and everyday settings. They are used to provide clear and detailed explanations of how something works or why something happens. These types of texts are essential for readers who want to understand processes, causes, effects, or concepts more deeply. Whether it’s a science textbook, an instruction manual, or a news topic, explanatory texts help break down complex ideas into digestible, logical steps. To write a good explanatory text, one must use a structured approach, simple language, and relevant examples. Below is a detailed discussion, including an example of an explanatory text and tips for writing your own.
Understanding Explanatory Texts
What is an Explanatory Text?
An explanatory text is a type of nonfiction writing that aims to explain a subject to the reader. It answers questions like how does this work? or why does this happen? It is different from persuasive or narrative writing because it focuses solely on providing facts, explanations, or reasons rather than opinions or stories.
Key Features of Explanatory Texts
- Clear Purpose: The main goal is to explain a process or concept.
- Logical Structure: Ideas are presented in a step-by-step or cause-and-effect format.
- Impersonal Tone: These texts are often written in the third person to maintain objectivity.
- Use of Examples: Good explanatory texts use real-life examples to clarify abstract ideas.
- Technical Vocabulary: Specific terms may be used, especially in scientific or technical topics, but they should be explained clearly.
Example of Explanatory Text
Title: How Photosynthesis Works
Photosynthesis is a natural process by which green plants, algae, and some bacteria convert light energy into chemical energy. It is one of the most important biological processes on Earth because it provides the oxygen we breathe and the food we eat.
Photosynthesis takes place mainly in the leaves of plants, where chloroplasts are located. Chloroplasts contain a green pigment called chlorophyll, which captures sunlight. When sunlight hits the chlorophyll, it triggers a chemical reaction that splits water molecules absorbed by the plant’s roots. This process releases oxygen into the air and combines hydrogen from the water with carbon dioxide from the air to create glucose, a type of sugar. This sugar serves as food for the plant and helps it grow.
The overall chemical equation for photosynthesis is:
6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
In simpler terms, this means that six molecules of carbon dioxide and six molecules of water, using light energy, are transformed into one molecule of glucose and six molecules of oxygen.
Photosynthesis is essential for life on Earth. Not only does it produce oxygen, but it also forms the basis of the food chain. Without photosynthesis, plants could not grow, and animals, including humans, would not have food or air to breathe.
Elements Found in the Example
Introduction
The beginning of the example explains the importance of the process being described photosynthesis. This draws the reader’s attention and sets the context for the explanation.
Logical Sequence
The explanation follows a clear, logical order: it starts with what photosynthesis is, where it occurs, how it works step by step, and why it matters. Each part builds upon the previous one to ensure understanding.
Use of Scientific Terms
Words like chloroplasts, chlorophyll, and glucose are used, but they are all explained in a simple and understandable way. This helps readers who may not have a science background grasp the idea more easily.
Visual Aid Support (Optional)
Although this topic does not include images, in other contexts, diagrams or charts are often included in explanatory texts to support the written explanation.
How to Write Your Own Explanatory Text
Choose a Topic
Select a topic that you know well or can research thoroughly. Good topics include natural processes, technical systems, historical events, or how-to guides.
Structure Your Text
Organize your text into an introduction, body, and conclusion. The introduction should state what you will explain. The body should present the explanation in a clear sequence. The conclusion should summarize the key points or restate the importance of the topic.
Use Clear Language
Use simple, direct sentences. Avoid jargon unless necessary, and explain any difficult terms you use. The goal is to make the reader understand, not to impress them with vocabulary.
Add Examples
Support your explanation with real-life examples, analogies, or familiar references. This makes your text more relatable and easier to understand.
Edit and Revise
After writing your explanatory text, read it over to check for clarity, grammar, and structure. Consider asking someone else to read it and give feedback.

Common Mistakes to Avoid
Being Too Vague
Make sure your explanation is detailed enough. Don’t assume the reader already knows the topic.
Overcomplicating the Language
Even if the subject is complex, the language should remain simple and clear. Avoid overly technical expressions unless they are properly defined.
Lack of Organization
If the structure is messy, the reader will have trouble following your explanation. Stick to a logical order and use paragraphs wisely.
Explanatory texts are powerful tools for communicating ideas clearly and effectively. Whether you’re writing about science, history, or everyday processes, the key is to remain structured, factual, and focused. The example of photosynthesis above shows how a well-organized explanatory text can break down a complex idea into something understandable. By following simple guidelines and using relevant examples, anyone can master the art of writing explanatory texts. With practice, your explanations will become not only informative but also enjoyable to read, making you a more effective communicator in any field.
