>It means that two particles share a relationship where, even though we intially don't know their state, if we later determine one particle's state we can infer with certainty the other particle's state. except that's not the whole truth either. A pair of gloves in separate boxes fits your description but aren't entangled, they always have a concrete state (hidden variables).
