ひらめき

ひらめき
noun
flash of inspiration; sudden idea
1. flash of inspiration; sudden idea; stroke of genius
A sudden, intuitive idea or insight that comes to mind without deliberate thought. Derived from the verb ひらめく (to flash, to strike upon an idea).

USAGE:
ひらめき is usually written in hiragana. It emphasizes the spontaneous, intuitive nature of an idea, as opposed to something arrived at through logical reasoning.

COMMON COLLOCATIONS:

  • ひらめきが()まれる (an idea is born)
  • ひらめきを()る (get an inspiration)
  • 一瞬(いっしゅん)のひらめき (a momentary flash)
  • ひらめきがある (have a flash of inspiration)

SIMILAR WORDS:
アイデア is the loanword for "idea" and is more general. (おも)いつき means "idea" or "thought" but can carry a negative nuance of being half-baked or impulsive. ひらめき always implies something positive — a creative or clever insight.
