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, and note one piece of evidence for each reason. A good plan turns a blank page into a clear roadmap.
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.
