IPA: /ɪˈpɪfəni/
KK: /ɪˈpɪfəni/
A sudden and clear understanding of something important, often leading to a new perspective or insight.
After weeks of confusion, she had an epiphany that helped her solve the problem.
Epiphany is derived from the Greek "epiphaneia" (meaning manifestation or appearance), which is composed of "epi-" (meaning upon) and "phaino" (meaning to show or to appear). The term originally referred to a sudden realization or insight, often seen as a divine manifestation.
Think of a moment when something is 'shown' ('phaino') to you 'upon' ('epi-') your understanding — that's what an epiphany feels like, a sudden insight or revelation.
