    Structure of an Expository Essay

    It has a particular structure that contributes to its properness and credibility. Its structure includes the following key points:

    1. A strong, concise, and defined thesis statement in the first paragraph that follows the guidelines outlined in the main topic of discussion.
    2. Each body paragraph should be connected with at least 1-2 sentences that demonstrate how each idea leads into the next and how they work together to support the writer’s position. This enables the reader to follow and understand the essay’s argument.
    3.  Evidential support in body paragraphs in the form of facts, statistics, or anecdotes should be provided to allow for clarity and direction throughout the essay. However, this type of writing does not always allow for a great deal of statistical or factual evidence.
    4. Pinch of creativity and artfulness are not commonly associated with essay writing, but descriptive essay writers should add a bit of creativity to make their work enjoyable and leave a lasting impression on the readers.
    5. Its concluding paragraph should not restate the essay’s thesis but rather readdress each paragraph’s evidential support. This leaves an immediate and lasting impression on the reader’s mind.

    Main Parts of an Expository Essay

    The structure of expository writing can vary depending on the scope and demands of a particular topic. However, regardless of its purpose, it should have at least five sections: the introductory section, first body paragraph, second body paragraph, third body paragraph, and a conclusion.

    Each section discusses different things that all tie up to the main idea of the essay:

    Introduction

    Like any other essay, it must begin with an introductory paragraph. This paragraph serves as an attention grabber for the readers. Therefore, the writer should begin by briefly introducing their essay’s topic and providing a thesis statement that summarizes what they will say in the rest of the paper.  The thesis statement should be clear, concise, and defined to avoid repeating what will be covered in the rest of the essay.

    Body paragraphs

    The first body paragraph of this essay should focus on one of the writer’s main points and provide evidence supporting the point. Skillful writers will typically provide two-three supporting points- reasons, facts, quotations, statistics, examples, or a mix of both.

    Both the second and third body paragraphs should follow the same pattern- each with a point that supports the thesis statement, to provide the reader with enough detail to be convinced of the writer’s arguments and fully understand the concept being discussed or explained. However, it is vital to understand that some sections may require further explanations, thus separating the information into multiple paragraphs.

    It is recommended that writers organize their body paragraphs logically with clear transitions to explain their ideas. For instance, if a writer describes a process, they may use the chronological format to demonstrate the definite time sequence in which the steps need to happen.

    Conclusion

    The essay’s concluding paragraph provides a concise summary of the body paragraphs, but writers should be careful not to restate what has already been written. Instead, to write an effective conclusion, look back at the main idea of each paragraph and try to summarize the point or thoughts using words that are different from those that have been used within the paragraphs. However, refrain from introducing or including new points in the concluding paragraph.

    tip

    Always ensure to conclude your essay in a reader-engaging way, stay clear and be very objective in presenting your thoughts, ideas, or points.

    Process of Writing an Expository Essay

    For most careers, expository writing is an essential daily requirement. Understanding and mastering the process of writing an essay can benefit writers, including students.

    Here is the practical process of writing it:

    Prewriting/outline

    • Write the topic sentence in the introductory paragraph, stating the thesis or central idea of the essay. The thesis should be clearly stated, and it should be objective and neutral.
    • The three body paragraphs should each cover a different point that develops the essay’s thesis, and evidence should be provided to validate the points.
    • The conclusion should reinforce the thesis and the main supporting ideas, and new facts or points should not be introduced in the conclusion.
    • The essay should be drafted in third person pronouns and avoid the use of I or you pronouns. This is because expository essays discuss an event, situation, or the views of others and not a personal experience.

    In this phase, writers are advised to review, modify, and reorganize their writing to achieve the best version.

    The writer should ensure that:

    • The essay provides an unbiased analysis that unfolds logically using relevant supporting evidence
