Mini Lesson
An argument essay tries to convince the reader that a particular position is correct. The engine of every argument essay is the thesis statement — a single sentence that states your position on a debatable topic and hints at the reasons you will use to defend it.
What Makes a Good Thesis?
- Arguable — a reasonable person could disagree with it. Facts are not theses.
- Specific — it names the exact position, not a vague opinion like "it is good."
- Supportable — you can back it up with evidence, examples, and reasons.
- One sentence — not a question, not a list, not an announcement.
Weak Thesis vs Strong Thesis
- Weak: "Social media is popular." (fact — no argument possible)
- Weak: "Should kids use phones at the dinner table?" (question — not a position)
- Weak: "Screen time has pros and cons." (too vague — no side is taken)
- Strong: "Families should ban phones at the dinner table because they interrupt conversation, create pressure to stay online, and reduce face-to-face family time."
The Argument Essay Structure
- Introduction — hook, background, and thesis statement.
- Body Paragraph 1 — Reason 1 + evidence + explanation.
- Body Paragraph 2 — Reason 2 + evidence + explanation.
- Body Paragraph 3 — Reason 3 + evidence + explanation.
- Conclusion — restate thesis, summarize reasons, call to action.
Planning Before You Write
Before writing a single sentence of your essay, spend five minutes planning. Jot down your thesis, list three reasons that support it, note one piece of evidence for each reason, and name the counterargument you will answer. A good plan turns a blank page into a clear roadmap.
Words to know
thesis statement
One sentence that states your arguable position and signals your main reasons.
arguable
Capable of being disagreed with; not a fact that everyone already accepts.
claim
An assertion or position you are trying to prove in your essay.
evidence
Facts, statistics, examples, or quotations that support a reason.
counterargument
The opposing view that you must acknowledge and then refute in your essay.
body paragraph
A paragraph that presents one reason plus evidence to support the thesis.
Tip: test your thesis by asking "Could someone reasonably disagree with this?" If the answer is no, it is a fact, not a thesis. A strong thesis always invites debate.
