I don’t know if they would have risked to jump in Korean 🇰🇷

Sentence info.

The sentence is segmented as follows:
• "그들이" – "그들" means “they” and "이" is the subject particle, making it “they” as the subject. (Romanized: geudeuri)
• "점프할" – derived from the verb "점프하다" (“to jump”), the verb stem "점프하" has its future/attributive form converted to "점프할," which functions as a modifier for the noun that follows. (Romanized: jeompeuhal)
• "위험이" – "위험" means “risk” and "이" is the subject marker attached to it. (Romanized: wiheom-i)
• "있는지" – from "있다" (“to exist” or “to be present”), this form creates an indirect yes/no question clause meaning “whether there is”. (Romanized: itneunji)
• "모르겠습니다" – from "모르다" (“to not know”), the phrase "모르겠습니다" is a formal expression meaning “I do not know”. (Romanized: moreugesseumnida)

Tips to remember:
• Notice how "점프할" (the attributive form of a verb) directly modifies the following noun "위험" to express a specific type of risk (“the risk of jumping”).
• The “-인지” structure ("있는지") is a common way in Korean to indicate an indirect question embedded within a sentence (similar to “whether… or not” in English).
• The sentence ends with "모르겠습니다" to politely state uncertainty.

Alternate ways to express “I don't know if they would have risked to jump”:
• "그들이 점프할 위험을 감수했는지 모르겠습니다."
 (Romanized: geudeuri jeompeuhal wiheomeul gamsuhaesseotneunji moreugesseumnida.)
• "그들이 점프하는 위험을 감수했는지 잘 모르겠습니다."
 (Romanized: geudeuri jeomppeuhaneun wiheomeul gamsuhaesseotneunji jal moreugesseumnida.)

Both alternatives incorporate "위험" (risk) and the verb "감수하다" (to take, to risk) to express the idea of having risked jumping.
