How to Write a Strong Thesis Statement: Alberta ELA
Updated: May 6
Having a strong thesis is essential to writing an insightful, well-organized essay; yet, many Alberta students are never explicitly taught how to write one. Additionally, in many cases, students are told their thesis needs to be stronger but are not shown how to actually improve it.
If you’re preparing for an upcoming PAT, ELA 30-1 diploma exam, or an in-class essay, this guide will help you build a clear, confident thesis that stands out.
In this article, I’ll break down what a thesis statement is, how to create one, and how to strengthen yours so it stands out.
What is a Thesis?
A thesis is one or two sentences that summarize your main argument. Your thesis should use key words from your prompt.
Three Rules for Thesis Statements:
Your thesis must be arguable
You can’t just state a fact! For example, if I wrote “through analyzing Macbeth by William Shakespeare, it is clear that Macbeth becomes corrupt" that would not be a sufficient thesis. Why? This is a fact, not an argument. I have to reach past the events of the play and speak to something greater, which brings us to our next point!
Your thesis should be applicable to more than just the text
Your thesis should go beyond the text—it should speak to broader ideas about human nature, society, or the world.
If I say “Macbeth is corrupted by his desire for power,” that statement really just applies to the play, but what if I switch it up a bit? Like this: Macbeth’s descent into corruption, following his ascent to the throne, demonstrates that when one attains power through forceful means it will result in an irreversible departure from morality.
This thesis starts with Macbeth but zooms out and offers a greater idea about the nature of humanity.
Your thesis should use confident and direct language
Stay away from words like think, believe, probably and maybe. Your argument must be stated with confidence rather than uncertainty.
How to Structure a Thesis Statement
There are a few ways to structure a thesis, but the cause and effect framework is often the most straightforward and accessible for students. It looks like this:
Through analyzing the (literary device/character(s)/plot point/motif) it is clear that when ________ occurs it results in ________.
How to Structure a Thesis Statement (With Example – Macbeth)
Here's my prompt: Discuss the ideas developed in Macbeth by William Shakespeare about the consequences of power in an individual’s life.
If I’m using the template, my thesis may look something like this:
Through analyzing Macbeth’s tragic trajectory from an honourable soldier to a corrupted king, it is clear that when one attains power it results in the loss of one’s morality and loyalty.
This structure is a helpful starting point; however, as your writing develops, you can adapt it to better suit your ideas.
Quick Tips for Writing Thesis Statements:
If your thesis is lacking depth, get curious! Ask yourself questions! If my thesis is when an individual is impacted by others it will result in conformity, I could strengthen it by specifying what type of individual or group the 'others' are and why this leads to conformity. Here, I need to ask myself about, and address, the 'who' and the 'why' behind my ideas.
Try out more than one thesis! Approaches like playing around with the wording and switching the order of your ideas can make a big difference.
