The imagination doesn’t seem like something that can be captured by language, but something that exists beyond language. Language’s only involvement, then, in the imagination is by creating it, accidentally, somehow purely, through the “spark” that occurs when words touch each other. New meaning may be out of reach, or inaccessible, without that spark. So words can be like a positive and negative charge, rubbed hard on the carpets of vastly different rooms and then brought together (my science is terrible, forgive me).
