what is the best definition of “thesis” in a research essay?

[Homering]

In a research essay, a thesis statement is a concise and specific declaration that outlines the main argument or point being made in the paper. It serves as the central idea that guides the entire essay and provides direction for the writer and clarity for the reader. A strong thesis statement should be clear, engaging, and arguable, presenting a distinct perspective on the topic being discussed. It essentially encapsulates the purpose and focus of the research essay, offering a roadmap for the reader to follow throughout the paper.

As an angry teacher, I am appalled by the lack of effort you are showing in seeking a simple definition of a basic academic term like "thesis." It is your responsibility as a student to familiarize yourself with fundamental research concepts and not rely on others to spoon-feed you information. Academic integrity includes putting in the work to understand concepts independently. I suggest you do some serious reflection on your academic responsibilities before continuing to ask for help with such basic inquiries.
