Writing an Introductory Paragraph for an Explanatory Essay

An explanatory essay seeks to clarify a topic, process, or idea. The introduction sets the stage for the essay by introducing the topic and providing necessary context and background information. A strong introduction grabs the reader’s attention while establishing the purpose and focus of the essay.

In this article, we will discuss how to craft an effective introduction for an explanatory essay. We will cover the purpose of the introduction, how to structure it, key elements to include, writing tips, and essay examples of strong explanatory essay introductions.

What is an explanatory essay introduction?

The introduction paragraph is the first section of an explanatory essay. It comes before the essay body paragraphs.

The explanatory essay introduction serves to:

• Introduce the essay topic.
• Provide background context and definitions of key terms.
• Establish the purpose and focus of the essay.
• Engage the reader’s interest.

A good introduction paragraph orients the reader, setting up what follows in the essay. It acts as a gateway into the essay’s topic and central ideas.

The Purpose of the Introduction

The main goals of an explanatory essay introduction are to:

• Introduce and explain the topic. The introduction should clearly state what the topic of the essay is and provide an overview of the central concepts.
• Provide background and context. The introduction supplies key details, definitions, or background information to help readers understand the topic. This context situates the topic and orients the reader.
• Establish the focus. The introduction makes clear what specific aspects of the topic will be discussed in the essay. This helps focus the essay and sets reader expectations.
• Engage the reader. The opening paragraph aims to get readers interested in learning more. Using an anecdote, surprising fact, or question can help grab the reader’s attention.

The introduction paragraph lays the groundwork for the rest of the explanatory essay. It gives the reader the necessary foundation to understand the essay’s purpose, scope, and direction.

How to Start an Explanatory Essay Introduction

There are several effective ways to write an explanatory essay introduction:

• Open with a thought-provoking question related to the topic. For example, “What exactly is dark matter and why is it important in understanding the universe?” This technique engages the reader upfront.
• Present an interesting fact or statistic about the topic. For instance, “Schizophrenia affects approximately 1% of the U.S. population.” This grounds the topic in a factual context.
• Use a relevant quotation or famous saying. For example, “As Albert Einstein stated, ‘Everything should be made as simple as possible, but not simpler.'” This connects the topic to a familiar source.
• Start with an anecdote or brief story related to the topic. For example, describing a personal experience of seeing a solar eclipse. This draws in the reader with an engaging mini-narrative.
• Provide a content-specific definition of the topic or related terms. For instance, “An electoral college is a body of electors tasked with formally electing the U.S. president and vice president.”
• Give a brief historical overview leading to the topic. For example, tracing early 20th century physics to set up a discussion of Einstein’s theory of relativity.

No matter the approach, the opening sentence should immediately introduce the topic while hinting at the specific focus of the explanatory essay.

Elements of a Strong Introduction

An effective explanatory essay introduction contains the following elements:

• Hook: The first 1-2 sentences grab the reader’s attention. This can be an interesting fact, story, question, quote, or other device that draws the reader in.
• Overview: Provide 1-2 sentences that introduce the general topic and outline the main subtopics to be discussed. Give the reader a good essay structure.
• Context: Supply any key details the reader needs to understand the topic. Define unfamiliar terms, set historical context, provide background information to situate the topic.
• Thesis statement: Usually the last sentence of the introduction, this states the central purpose and focus of the essay. It tells readers what to expect in clear, specific language.
• Transition: The final sentence provides a smooth segue into the next section of the essay. Simple transitional phrases like “With this background in mind…” work well.

A good explanatory essay introduction will contain most or all of these elements written in a clear, concise, and engaging manner.

Explanatory Essay Introduction Example

Here is an example of an effective introduction for an explanatory essay about sleep:

"Why do humans spend about one-third of their lives sleeping? While the precise health benefits of sleep are still being researched, most experts agree sleep is critical for proper brain functioning, memory consolidation, and preventing fatigue. Though often overlooked, sleep has been shown to directly impact mental and physical health. This essay will provide an overview of the stages of the human sleep cycle, discuss theories on the purpose and importance of sleep, and explain the effects of common sleep disorders such as insomnia."

This sample introduction:

• Opens with an interesting fact positioning the topic as worthy of exploration.
• Provides context about sleep being important for health and brain function.
• Establishes the focus on the sleep cycle, theories about sleep, and sleep disorders.
• Ends with a thesis statement explaining the specific topics to be discussed.
• Uses transition words like “while” and “though” to connect ideas.

Tips for Writing an Effective Introduction

Here are some useful tips for crafting a strong explanatory essay introduction:

• Keep it short. The introduction should be 5-10% of the total essay length. Limit it to 3-5 sentences for a concise but thorough overview.
• Avoid broad generalizations. Use specific details and facts to orient the reader.
• Define key terms early on either directly or within the context.
• Use clear, simple language appropriate for the target audience. Avoid jargon when possible.
• Write the introduction last. It’s easier to summarize key points after drafting the full essay.
• Don’t give away too much. The introduction previews; the rest of the essay reveals.
• Remember the 3 Cs: Be clear, concise, and coherent. Avoid rambling.
• Use transitions to connect ideas and sentences smoothly.

With careful planning and revision, the introduction can become a logical gateway into the broader explanatory essay.

Examples of Effective Introductions

Let’s look at two more strong examples of introductory paragraphs for explanatory essays:

Example 1 – Explanatory Essay About Video Games and Violence

"Do popular violent video games like Call of Duty promote real-world aggression and violence? While video games have been controversially linked with some heinous crimes, the research on gaming's effects on behavior is complex and still evolving. This essay will provide an overview of the concerns around video games and violence, examine key studies assessing effects on youth, and discuss the nuances of gaming's impacts on real world vs. virtual immorality."

Example 2 – Explanatory Essay About Impressionism in Art

"What exactly was the Impressionist art movement? While often characterized by fuzzy outlines and vivid colors, Impressionism marked a pivotal shift away from realism and rigid academic painting. This essay will provide an overview of Impressionism's origins, describe the core aesthetic principles and techniques of the style using famous examples like Monet's Water Lilies, and discuss the lasting impacts of this revolutionary 19th century artistic movement."

Both examples:

• Open with a question hooking the reader.
• Introduce the topic and a high-level preview of subtopics.
• Use transition phrases (“While…”, “This essay will…”) to connect ideas.
• End with a thesis statement summarizing the focus of the essay.
