Grammar
이로써
Meaning
Expertirosseo
A formal adverb meaning 'with this' or 'thereby,' used to refer back to something just described and introduce the result, consequence, or milestone that follows from it. Common in news reports, formal announcements, and ceremonies.
Form
이로써 is a fixed adverb — it doesn't conjugate or attach to other words. It stands at (or near) the beginning of a sentence, referring back to an event or fact stated in the previous sentence, and is followed by a clause describing the resulting outcome: [previous sentence]. 이로써 [result clause].
Examples
이로써 한국은 우주 발사에 성공한 나라가 되었다.
With this, Korea became a country that succeeded in a space launch.
이로써 회의를 마치겠습니다.
With this, I will conclude the meeting.
이로써 모든 준비가 끝났다.
With this, all the preparations were complete.
Common mistakes & nuance
이로써 belongs to a formal, mostly written or ceremonial register (news, official announcements, speeches); it rarely appears in everyday conversation. It literally combines 이 ('this') + 로 ('by/with') + 써 (an old form emphasizing means), but is used today as a single fixed word.
Similar grammar
- 그래서
그래서 is a common, everyday connector meaning 'so/therefore,' usable in casual speech. 이로써 expresses a similar cause-result relationship but is much more formal and often marks a significant conclusion or milestone, not just any result.
- -에 이어
-에 이어 ('following ~') connects two events to show one happening right after another, without necessarily implying a conclusion. 이로써 specifically frames what follows as a resulting outcome or milestone reached because of what was just mentioned.
