Analysing How Essays Develop Ideas: The Rhetorical Situation, Toulmin and Structure

Hook: the magic trick

A magician shows you an empty hat and pulls out a rabbit. A good audience says Wow. A curious audience asks How did they do that? Analysing a text is being the curious audience. You already know what an essay says (Lesson 2 mapped it). Now you ask how it builds and develops its ideas: through structure, evidence, reasoning and appeals to the reader.

The rhetorical situation

Every informational text is written by someone, for someone, for a reason, at a time. Before analysing the structure, name the situation:

• Writer: who is speaking, and why should we listen? (ethos)
• Audience: who are they trying to reach? What do those readers already believe?
• Purpose: to inform, explain, persuade, reflect, entertain, or a mix?
• Context and timing: what is happening that makes this text matter now? (kairos)

Then ask the analysis question: How do the parts of this text work together to develop its idea for this audience?

The Toulmin model: how arguments really work

Philosopher Stephen Toulmin described everyday arguments as having more parts than claim + evidence:

• Claim: what the writer wants you to accept.
• Grounds: the data or evidence.
• Warrant: the (often unstated) assumption that links the grounds to the claim.
• Backing: support for the warrant.
• Qualifier: words that limit the claim (probably, in most cases).
• Rebuttal: conditions where the claim would not hold.

The warrant is the most useful part for analysis. When an argument feels wrong but the facts are true, the problem is usually a weak or hidden warrant.

A personal essay to analyse

What the Ice Taught Me

(A personal essay written for this website.)

Every December, the night the temperature finally stayed below minus ten, my father dragged the garden hose out of the basement and flooded the backyard. By morning there was a rink, bumpy and grey, with a maple leaf frozen into one corner.

I thought a rink was something you made once. I was wrong. Every night that winter, after supper, he went out with a bucket of warm water and a squeegee. He filled the cracks our skates had cut. He scraped off the snow. He did it when it was minus twenty-five and the wind came straight off the field. He did it when nobody had skated all day.

When I was twelve I asked him why he bothered. Nobody even used it today. He shrugged. If I skip one night, the cracks get deeper. Skip three, and it's not a rink any more.

I have thought about that answer more than almost anything he has told me. I see it in the friend I text every week even when there's no news, in the trumpet I practise for twenty minutes even when the concert is months away, in the neighbour who shovels the whole sidewalk and not just her own. We like to believe that good things are built once, in a big moment. Mostly, they are kept alive in small ones.

The rink melts every March. But the lesson freezes a little harder every year: anything worth having needs a little care every day.

How a personal essay develops its idea

A personal essay argues too, but quietly. It usually moves from the specific (a scene, a person, an object) to the general (an insight about life). Its argument is the reflection: the writer shows how they came to understand something. Its power comes from structure: the reader lives the scene first, so the insight feels earned, not preached.

Ordering claims for effect

In a persuasive essay, the order of claims is also a choice:

• Climactic order: weakest to strongest, so the essay ends on its best point.
• Strong start: strongest first, to grab sceptical readers.
• Concession first: admit the opposing view early to build trust (ethos), then answer it.
• Problem → cause → solution: common in reports and editorials.

When you analyse an essay, say not only what the order is but why it helps this audience.
