Common Writing Errors

Even advanced learners often slip up on spelling, word spacing, and the written-versus-spoken distinction. This lesson reviews the most frequent errors in Korean composition.

Spelling: 'doe' vs. 'dwae', 'an' vs. 'anh'

'dwae' is a contraction of 'doeeo', so write 'dwae' wherever it makes sense to expand it to 'doeeo'. 'an' is an adverb, whereas 'anh' is a contraction of the verb 'anihada'.

결과가 다르게 나와도 당황하지 않아도 된다.

gyeolgwaga dareuge nawado danghwanghaji anado doenda.

Even if the result differs, there is no need to panic.

이 방법은 효과가 검증되지 않았으며, 사용해서는 안 된다.

i bangbeobeun hyogwaga geomjeungdoeji anasseumyeo, sayonghaeseoneun an doenda.

This method has not been verified and must not be used.

Spacing: bound nouns and particles

Bound nouns such as 'geot', 'su', 'ba', and 'ttae' are spaced from the preceding word, while particles such as '-mankeum', '-daero', and '-ppun' are attached.

그 일을 한 지 삼 년이 지났다.

geu ireul han ji sam nyeoni jinatda.

Three years have passed since doing that work.

할 수 있는 만큼 노력한바, 목표를 달성하였다.

hal su inneun mankeum noryeokhanba, mokpyoreul dalseonghayeotda.

Having striven as much as possible, the goal was achieved.

Confusing particles and endings ('-roseo' / '-rosseo', '-meuro' / '-meumeuro')

'-roseo' marks a qualification or status, while '-rosseo' marks a means or instrument. '-(eu)meuro' indicates a reason, whereas '-(eu)meuro(sseo)' indicates a means, so the two must be clearly distinguished.

교사로서 책임을 다함으로써 신뢰를 얻었다.

gyosaroseo chaegimeul dahameurossseo silloereul eodeotda.

As a teacher, trust was earned by fulfilling one's duty.

Written vs. spoken register

Avoid colloquial expressions such as 'geunde', 'eomcheong', 'doege', and '~geodeunyo' in formal writing; replace them respectively with 'geureonde', 'maeu', and '~gi ttaemunida'.

이 자료는 매우 중요하다. 그런데 출처가 불분명하다.

i jaryoneun maeu junghyohada. geureonde chulcheoga bulbunmyeonghada.

This material is very important; however, its source is unclear.

💡 Tip: When proofreading, substitute 'ha/hae' for 'doe/dwae'. If 'hae' sounds natural, 'dwae' is correct; if 'ha' sounds natural, 'doe' is correct.
