Why do Korean novels have so many sound effects?

A fight scene in a Korean web novel arrives with its own soundtrack. Kwang. Chaeng. Puk. A line of dashes and then a sound, standing alone on the page like a panel in a comic. English readers of translated Korean fiction notice the sound effects first and ask why there are so many. The Korean has even more, and a whole category of them doesn't make any noise.

What the words are

Korean has two families of these words. 의성어 (uiseongeo) are sound words, the ones English also has: a crash, a bang, a knock. 의태어 (uitaegeo) are mimetic words, words that imitate a movement, a texture, a feeling or a look, and those are the ones English mostly lacks. There's a word for the way a big man walks, a word for eyes glittering, a word for a heart pounding, a word for something being sticky or soft or flickering. They're built on a sound-symbolic system where a vowel change makes the same word smaller or brighter, so 반짝 is a twinkle and 번쩍 is a flash.

Why web novels use so many

Because they're fast. A Korean web novel chapter is written in a day for a reader on a phone, and a mimetic word does in two syllables what a descriptive sentence does in twenty. A hunter's blade goes through a monster and the writer types one word for the sound and one for the wet spray, and the reader sees the panel.

They carry tone, too. Rofan uses the soft, bright ones for a heroine's blush and a dress's rustle; hunter novels use the heavy, dark ones for footsteps and impacts; comedy stacks them for effect. A Korean reader gets mood from the vowels before reading the sentence, and a writer who's good at these words has a texture a translation will struggle to keep.

And there's the standalone sound effect, the one-word line between paragraphs. Korean web novel formatting borrowed it from comics, and it's now a genre convention: a beat, a break, a little drumroll before the next thing. English fiction doesn't do this outside of comics, so it looks odd on the page.

How translators handle them

One way is to keep them, romanized. Kwang and puk and hwaruk appear as-is, and the reader learns them. It's faithful to the page's rhythm and the comic-book feel survives. What goes missing is meaning: an English reader doesn't know that 쿵 is a heavy thud and 콩 a light one, so the vowel system that Korean readers hear is gone, and the words become noise.

Another swaps in an English sound. Kwang becomes crash, chaeng becomes clang, puk becomes thud. This works for the sound words, since English has plenty. It fails for the mimetic ones, because there's no English sound for a glare or a sway, and the translator ends up inventing something or dropping it.

The third, and the standard for licensed editions, rewrites the word into the sentence. The mimetic word for a heart racing becomes "her heart was going hard enough to hurt"; the word for a man's heavy walk becomes a verb, "he lumbered." The standalone sound-effect line gets folded into the next paragraph or cut. This reads most like English prose. The loss is the page's rhythm, and sometimes the writer's ear: a novel that was punchy and percussive in Korean can come out smooth and a little flat.

What we'd choose

The third way for the mimetic words, always, because leaving them romanized is leaving them untranslated. For the sound words, the second way in prose, and the first way only in the rare book where the sounds are a joke the characters are in on. For the standalone sound-effect line, we'd keep a few, at the biggest beats, and fold the rest, because a page of them is a comic and a page of none is a different book than the writer wrote.

Under all of it, one rule: the same Korean word comes out the same way each time. If the heroine's heart does one thing in chapter three, it should do the same thing in chapter three hundred, and that's the kind of small consistency a long translation has to fight for.

How to read them comfortably

When you hit a bare sound on its own line, hear it as a drumbeat and keep going. When a sentence describes a movement more vividly than English usually bothers to, that's a mimetic word that survived. That steadiness across a whole book is the thing we care about; for your next Korean novel, read it in Crossleaf.
