-거들랑①
-거들랑①: If / When That Holds — Connective Condition
Connective: if / when the preceding fact holds or comes true — condition linker.
How to form it
| When | Form | Example |
|---|---|---|
| Verb / adjective stem | -거들랑 | 오거들랑 / 알거들랑 / 바쁘거들랑 |
| With sequel often imperative / advice | -거들랑 + command / advice | 오거들랑 말해 / 모르거들랑 물어 |
-거들랑① is a condition connective: if / when that is so — take the front as holding, then continue.
Curriculum sense: 조건. It links; it does not stop the sentence to lecture the listener. The ending job (②) is a different slot later in the book.
Why this is hard
Same letters appear as a sentence ending that informs (알거들랑 said alone). Learners mash both into one button. Here the stem opens a bridge to advice or a next act: 오거들랑 말해.
It also sits near -거든 and everyday -면. The coat is rarer and more pointed.
What it does
You set a condition, then tell what to do when it holds.
오거들랑 전화해.
모르거들랑 물어봐.
바쁘거들랑 나중에 해.
준비되거들랑 시작하자.
Front = condition. Back = often spoken next step.
Forms
Stem + -거들랑. Works with verbs and adjectives in the classroom core.
When not to use it
Do not use this slot for a lone ending that means you should know… — that is -거들랑② (later).
Do not replace every café -면 with -거들랑; it can sound stiff or old-fashioned.
Do not treat it as a noun particle.
Neighbours — and why they differ
| Form | Why it is not this slot |
|---|---|
| -(으)면 | Everyday if — lighter, broader. |
| -거든 | Close condition neighbour; different shape. |
| -어야 | Only if / must — necessity flavour. |
Ask: am I linking ‘if that holds’ into a sequel (often advice)? If yes, -거들랑①. If you are ending to inform, wait for ②.

Ending slot?
