What Is a Thesis? 

The definition of thesis (ˈθi sɪs, ˈθiːsɪs, the-sis, plural theses) in American English is the main idea presented in an essay. In other words, the central message of the piece. Behind every literary device and rhetorical strategy stands a thesis. Thesis statements don’t just appear at the beginning of your paper; they should be woven into every sentence you write. 

Your thesis statement will probably be one of two things: an assertion that something is true or an argument for why something should be done (or not done). 

What Is a Thesis Statement?

A Thesis statement is a sentence that contains the main idea of a written work.

What Is a Thesis in the Academic World? 

When it comes to the world of academics, the word thesis has another similar yet different meaning. 

A thesis is a long-form piece of writing, often a research paper, that is used as the final project of a university degree, like a master’s degree. 

What Is a Master’s Thesis?

A master’s thesis is a project that contains lots of original research and is used to cap off an academic degree. It is how a student takes an unproved statement and then proves it through extensive writing. 

When Would You Write a Thesis?

If you’re studying a language like Greek, Spanish, Arabic, or Late Latin, you’ll likely have to do an extensive study — and write a thesis — to prove your knowledge of the language. The main goal of a thesis is to establish the synthesis of knowledge that a student is capable of and ensure that they can operate well in the academic world. 

How Do You Start Writing a Thesis?

Before a student or researcher begins writing a paper, they must have a thesis statement. This thesis statement is one sentence that describes how you will support your argument and what evidence you will provide in your paper. In many cases, it is the last sentence of your introduction paragraph and appears again as the first sentence of the body paragraph:

A thesis statement usually evolves only after considerable reading, writing, and thinking has been done on your topic. Your thesis changes and develops as you write it, so by the time you arrive at the end, you will know what your paper is about and should be able to sum it up clearly in a sentence or two.

What Is the Etymology of the Word Thesis? 

The word thesis comes from the Greek word θέσις (thésis), which means “placement” or “setting.” The term was first used in English in 1632 by William Lilly. As time has progressed, the word has entered into many different languages, including Latin tithenai, French, and Middle English. 

Throughout its different stages of development, the word has remained relatively the same. However, this word’s collocations and more specific meanings have gradually changed over the years. 

Luckily, as long as you’re only sticking to English, thesis is a word with meanings that are relatively consistent and easy to understand!

One of the best ways to learn how to use a word is by seeing it in use in the context of actual-world sentences and conversations.
