What is the purpose of an introduction in an essay?

The purpose of an introduction in an essay is to set the stage for the reader and clearly state the thesis. An effective introduction serves several key functions: it grabs the reader's attention, introduces the main topic of the essay, and presents the thesis statement, which outlines the writer's main argument or point of view. This establishes the direction the essay will take and helps readers understand what to expect as they continue reading. By setting up the context and framing the argument, the introduction becomes a crucial foundational element that guides the reader through the subsequent content of the essay.
