A quantum system exists in multiple states? Superposition. When measured, this superposition, collapses into a single state. The superposition is thought of as a wave, measuring a particle in a wave collapses that part of the wave that contains the particle. When the measuring ceases does the system return to a superposition?
Not straight away. It's not instantaneous. First the particle has to manage decoherence, a sense of being lost. It sits on the back row being sniffed at by strangers. But yes, as soon as you stop measuring a particle the wave spreads back out, the particle returns to superposition of all its possible states.
A verb is a particle in an uncollapsed wave, it is very content with being in superposition with all it's possible states, as in the undigested cat/catty/catadom/caterwaul/decapitated and bloody mouse on carpet and many more. If you now pick out that particle, drag into onto the back row for questioning, whether you like it or not, or whether it likes it or not the verb becomes a noun called George or Kitty
