Meaningful coincidences that seem to defy probability — events connected by meaning rather than cause.
Coined by Carl Jung in the 1920s from Greek syn- (together) + chronos (time). Jung proposed it as an alternative to causality — some events are connected not because one caused the other but because they share meaning.
Jung invented synchronicity because science had no word for meaningful coincidence. Causality explains everything connected by mechanism — but what about the connections that feel meaningful without a mechanism? He refused to call it chance.
