-기로서니
-기로서니: Even If / No Matter How — Concede Then Reject
Connective: even if / no matter how — concede the premise, then refuse the expected conclusion.
How to form it
| When | Form | Example |
|---|---|---|
| Verb / adjective + -기로서니 | -기로서니 | 바쁘기로서니 / 알기로서니 / 어렵기로서니 |
-기로서니 grants a strong premise, then rejects the conclusion that people might expect — even so / no matter how…, still no.
Curriculum gloss: conceding the premise then rejecting the conclusion. It is concessive muscle, not soft café -지만.
Why this is hard
It looks like -기 plus decoration. The package is one classroom chunk: nominal -기 + 로서니. Learners also under-feel the reject: the point is not sympathy for the premise; it is shutting the door afterward.
Neighbours -어도, -은들, -을망정 sit nearby. This slot stays on the -기로서니 shape.
What it does
바쁘기로서니 약속은 지켜야 해요.
알기로서니 가만히 있을 수는 없어요.
어렵기로서니 포기는 안 해요.
돈이 없기로서니 그건 못 해요.
Front = granted (often extreme). Back = refused conclusion.
Forms
-기로서니 after the verb/adjective’s -기 nominal.
When not to use it
Do not use it for mild spoken even-if — -어도.
Do not drop -기 and invent bare 바쁘로서니.
Do not use it when you only mean soft but — -지만.
Neighbours — and why they differ
| Form | Why it is not this slot |
|---|---|
| -어도 | Lighter even if / though. |
| -지만 | But — plain contrast. |
| -은들 (nearby) | Related concession — different shape. |
Ask: am I granting a strong premise just to reject the conclusion? If yes, -기로서니. If soft even-if, stay with -어도.

Argument, careful speech, writing — pointed. Soft café even-if usually stays with -어도.
Need 아무리?
Often pairs with 아무리 / 아무리 …기로서니 for scale, but the ending itself carries the concessive reject.
