Wow! exclamation. A spontaneous expression of wonder or impressed surprise.
Wow appears at the edge of amazement. It captures the quick transition from expectation to astonishment and marks genuine impact in a single syllable.
The expression remains widely useful because it is brief, sincere, and flexible: it can signal delight, admiration, gratitude, or simple awe.
A global positive “Wow” moment came on July 20, 1969, when Apollo 11 landed on the Moon. It stunned the world and expanded what humanity believed was possible.
"OH WOW. OH WOW. OH WOW."
- Steve Jobs (reported by his sister Mona Simpson as his last words)
