Building Academic Vocabulary in Writing a Comment and Argumentative Essay

Ask a grades 9–12 class to write an argumentative essay and you will often get strong opinions wrapped in weak language. The ideas are there; the words to connect, concede, and qualify them are not. Academic argument runs on a specific vocabulary—claim, counterargument, concede, refute, warrant—and students who own that language write with a control that graders notice. Building it is not about handing out a list to memorize. Working from Writing a Comment and Argumentative Essay, here is how to make the vocabulary of argument stick through routines rather than rote.

Build a working word wall

A word wall earns its space only if students use it. Organize yours by the job each term does, not alphabetically, so a student stuck mid-paragraph can find the right tool:

• Words that assert: claim, contend, maintain, assert.
• Words that concede: admittedly, granted, while it is true that.
• Words that push back: however, nevertheless, refute, undermine.
• Words that connect evidence: demonstrates, illustrates, suggests, reveals.

Add terms as you meet them and point to the wall during writing time, so it becomes a living reference instead of decoration.

Teach vocabulary in context, not in isolation

Words learned from a definition fade; words learned from use last. Introduce each term inside a real argument. When you study a model op-ed, stop and name the move: “See how the writer concedes here before pivoting?” Students then imitate the move immediately in a sentence of their own. This applies naturally to the analysis of persuasive images in Analysing Cartoons – Step by Step, where students name the rhetorical technique a cartoonist uses and then borrow the same verb—exaggerates, satirizes, implies—for their own written commentary. Vocabulary sticks when it is a tool for a task, not an item on a quiz.

Routines that recycle the language

One exposure is never enough, so build lightweight routines that bring the words back:

1. Sentence stems of the day: post one stem—“While critics argue …, the evidence suggests …”—and have students fill it about the day's topic.
2. Vocabulary in reverse: give a strong sentence and ask which academic move it makes.
3. Upgrade this line: students take a flat claim and rewrite it using two wall words.
4. Weekly self-audit: students highlight academic verbs in their own drafts and count them.

These take minutes and, repeated across a unit, they align tightly with the Common Core writing standards' call for precise language and formal style.

Move vocabulary from recognition to production

The final step is the hardest: getting words out of students' heads and onto the page under pressure. Study of high-stakes persuasion helps here—when students examine the deliberate word choices in Analysing Political Speeches – Rhetoric and Stylistic Devices, they see academic and rhetorical vocabulary doing real work at scale, then carry that register into their own essays. Ask for a required quota—three wall words per body paragraph—in early drafts, then remove the training wheels as the language becomes automatic. When the vocabulary of argument is theirs, students stop writing loud opinions and start writing persuasive essays.
