🧾 Meaning & Background

“A bolt from the blue”, the English version of 마른하늘에 날벼락,
describes something completely unexpected and shocking happening out of nowhere.

Literally, it means “a lightning strike from a clear sky” –
used when an unforeseen misfortune hits someone with no prior warning.

💡 Did You Know?

• Lightning only occurs in storm clouds, so the image of it falling from a cloudless sky highlights how shocking and unnatural the event feels.

• Often used in emotional or dramatic life events:
  ✔ sudden breakup
  ✔ death in the family
  ✔ being fired unexpectedly
  ✔ surprise bills or scandals

• It’s the kind of shock that leaves you speechless – because you didn’t see it coming at all.
