What happens when a Korean character drops formal speech?

A translated novel will sometimes stop for a line like "he had stopped speaking to her formally," and the heroine reacts as if he'd kissed her. Nothing in the English dialogue changed. Something in the Korean did, and when a Korean character drops formal speech the whole room hears it.

What the verb ending is doing

Korean verbs end differently depending on who you're talking to. The polite everyday ending, 요 (-yo), and the stiff formal one, 니다 (-nida), are 존댓말, honorific speech, the register you use with elders, strangers, superiors and anyone you're being careful with. Drop the ending down to the bare verb and you're speaking 반말, banmal, the plain speech of friends, family and children. The same sentence, asking whether someone has eaten, can be said three ways, and each one is a claim about the relationship. There's no neutral. Every line of dialogue in a Korean novel is also a statement of where the two speakers stand.

What it means when it changes

A shift in speech level is an event. When the duke stops using honorifics with the heroine, he's either claiming intimacy or claiming rank, and which one it is depends on whether she's allowed to answer in kind. A younger man who drops formal speech with an older one is picking a fight. Two friends who suddenly go formal with each other are having the coldest argument in the book. A regressor who slips into banmal with a general he used to serve under, because in his memory they're old comrades, has just told everyone in the tent that something is wrong with him.

It also runs the romance. Korean love stories often keep the couple on 요 endings for hundreds of chapters, and the first banmal, the first bare verb, is a scene. Writers know their readers are listening for it.

How translators handle it

Most translations leave it out. English has no speech levels, the dialogue reads the same, and the translator trusts the story around it to carry the feeling. That's fine until it isn't: the chapter where the shift is the point arrives, and the English reader gets a heroine blushing at nothing.

Others narrate it. The translator adds a beat that the original didn't need, something like "she noticed he'd dropped the honorifics," and the reader is told what the Korean reader heard. It works, it's honest, and it's a little like a subtitle explaining a joke. Some translations go further and keep the Korean word, banmal, in the text, which readers who've watched a lot of Korean drama already know.

The ambitious option builds the register into the English. Formal speech gets titles, full sentences, no contractions: "Would you care to sit, my lady?" Plain speech gets first names, fragments and the ordinary shorthand of people who know each other: "Sit down, Elena." Then the drop is audible in English, because the reader hears the sentence loosen. It's the most skilled option and the riskiest, since English formality has its own class connotations and a duke who speaks in contractions can sound like a man who's been demoted.

What we'd choose

The third way, with the second as a safety net. Set a formal voice and a plain voice for each relationship early, keep them consistent across the whole book, and let the change be heard rather than announced. Then, on the one occasion per novel where the shift is the plot and the English can't carry it alone, add the narrated beat and don't apologize for it. The one to avoid is the mix, where a character is formal in chapter three and casual in chapter nine for no reason except that the chapters were translated on different days. Readers can't hear the Korean, but they can hear inconsistency, and it reads as the character changing their mind about someone.

How to read it comfortably

When a translated novel tells you that someone started speaking casually, take it as seriously as the characters do. It's the Korean equivalent of using a first name for the first time, of taking off a title, of being allowed in. And when the dialogue in a scene suddenly gets shorter and warmer with no explanation, that's probably the same thing done well. A book that keeps those voices steady from the first chapter to the last is doing quiet work on your behalf; find one and read it in Crossleaf.
