means A state where two or more particles become linked so that measuring one instantly tells you something about the other, no matter how far apart they are.

from From 'entangle,' rooted in 'tangle' — likely linked to Scandinavian words for seaweed or thorny brush, the kind of snarl that catches your boat or your sleeve. The physics sense was coined in the 1930s when Schrödinger, wrestling with the strangeness Einstein had just pointed out, called it 'Verschränkung' in German — folded-together-ness — translated into English as 'entanglement.' Einstein himself distrusted it enough to call it 'spooky action at a distance,' which tells you the tangle was never just a figure of speech.
