Etymology

Origin of synchronicity

First recorded in 1865–70 synchronicity for def. 1; 1950–55 synchronicity for def. 2; synchron(ous) ( def. ) + -ic ( def. ) + -ity ( def. )

Explanation

Ever step outside just as the sun comes out? Or pass by a street lamp at night, and it turns on at that moment, seemingly just for you? That's synchronicity, when things happen together, as if perfectly timed. If you're planning to lip-sync your next concert, you'll want to work on your synchronicity with your soundman. And speaking of music, if you're a rock-and-roll nerd, you're no doubt thinking of "Synchronicity," the megahit album by The Police, released in 1983. The term synchronicity was coined in the 1950s by the Swiss psychologist Carl Jung, to describe uncanny coincidences that seem to be meaningful. The Greek roots are syn-, "together," and khronos, "time."
