-기에 앞서(서)
-기에 앞서(서): Before Doing… — Prior to the Step
Connective: before the action named by -기 — prior step / preparation frame.
How to form it
| When | Form | Example |
|---|---|---|
| Verb + -기에 앞서 | -기에 앞서 | 시작하기에 앞서 / 말하기에 앞서 |
| With 서 | -기에 앞서서 | 시작하기에 앞서서 |
-기에 앞서(서) means before doing… — prior to the step you name.
Why this is hard
It sounds formal next to everyday -기 전에. Learners paste the heavy frame into café chat and sound like a memo. The job is sequenced preparation: before X, do Y — often in plans, notices, and careful speech.
What it does
You mark a prior step that should come first.
말하기에 앞서 자료를 읽으세요.
출발하기에 앞서 확인해요.
결정하기에 앞서 상의했어요.
시작하기에 앞서 이름을 적어요.
Forms
Verb + -기에 앞서 / -기에 앞서서.
When not to use it
Do not use it as the only soft ‘before’ in casual chat. Do not confuse it with -기 때문에 cause. Do not attach it when no prior step is intended.
Neighbours — and why they differ
| Form | Why it is not this slot |
|---|---|
| -기 전에 | Everyday before doing — lighter. |
| -은 후에 | After doing — opposite order. |
| -기에 따라 | Depending on — not ‘before’. |
Notices, presentations, and study plans love this frame. If the sentence only needs soft timing, do not climb the register for free.
Classroom examples should keep the meaning concrete: one clear scene beats three vague glosses. If a neighbour form already says the same thing more lightly, prefer the lighter tool unless register demands this one.
Ask: am I naming a careful prior step before X? If yes, -기에 앞서. If you need café before, -기 전에 is enough.
