Every sentence is shaped by the reader you imagine. Imagine the wrong reader and the sentence does the wrong work.
You speak to your grandmother differently than to a classmate, and to a professor differently than to your best friend. You drop honorifics with one and pick them up with another, without thinking.
That instinct, 눈치, the read of the room, has to be present in your writing too.
In writing, the reader is not in front of you. You have to imagine them well enough to anticipate where they will be confused, where they already agree, and where they will resist.
A particular animal: educated, sceptical by training, short on time, and reading dozens of pieces this week. They will not give you the benefit of the doubt.
Reasoning over emotion. They are moved by the strength of the argument, not by adjectives.
Assertion is cheap. They want claims backed by sources they can check.
Clarity over cleverness. None of this means cold writing, it means honest writing.
Write for someone short on time who has read three essays before yours and will read three after. Earn their attention on every line.
A Korean undergraduate, a professor, and an international journal reader are three different audiences.
A doctorate expects denser argument and shorter explanations; a first-year needs terms defined.
No need to define blockchain for an IEEE reader. You do need to define tokenomics.
Shape and tone, APA's hanging indent, IEEE's bracketed numbers. Break the expectation only on purpose.
Writing about Korea for a non-Korean reader? Chuseok, jeonse, hagwon each need a one-line gloss. For a Korean reader, do the opposite, explaining what they know reads as patronising.
Picture the one person who will read your essay. Who are they, exactly?
Audience is one of five elements. Map all five before you draft and you save yourself from rewriting the introduction three times.
| Element | The question it answers | From a real assignment |
|---|---|---|
| Purpose | What am I trying to do, argue, explain, evaluate, propose? | Argue the four-day week would harm Korean SMEs. |
| Audience | Who is reading, and what do they already accept? | Business readers, sceptical of mandates. |
| Context | What conversation is this entering? | The debate after Gyeonggi's pilot programme. |
| Genre | What form does the reader expect? | 1,500-word commentary, APA, six sources. |
| Voice | My relationship to topic and reader? | Engaged but professional, reasoning, not preaching. |
It is absolutely tragic that so many bright young Koreans are being crushed by a brutal job market that simply does not care about them.
Statistics Korea reported a youth (15–29) unemployment rate of 6.7% in February 2025, with involuntary part-time underemployment nearly double that (Statistics Korea, 2025).
The second version says something the first does not, here is what is happening, and you can check it. The first says only how the writer feels.
One claim, smartphone use delays sleep, written for three readers. Notice what each assumes, defines, and leaves out.
The op-ed allows “we” and a little colour; the essay defines the measure and cites it; the clinical version assumes the mechanism and compresses the rest.
Two short exercises. The first maps your reader; the second trades heat for evidence.
For the commentary essay you write this term, name all five elements in one line each.
Read your partner only the Audience and Voice lines. Can they guess your topic? If not, sharpen them.
Rewrite each over-heated line so it persuades through evidence. Invent a plausible source now; find a real one for the essay.
“University students today are completely overwhelmed by an insane workload that nobody cares about.”
“It is shocking how much plastic waste Korean delivery culture creates every single day.”
“AI is going to destroy education unless somebody finally does something serious about it.”
Read one revision aloud. Did the evidence change what the sentence is actually claiming?
