"Dead End" is a term used to describe a situation or location that has no exit or further progress. In urban planning, it often refers to a street or road that does not connect to another, leading to a cul-de-sac. This can create challenges for traffic flow and accessibility. In literature and film, "Dead End" can symbolize a character's inability to move forward in life or a plot that reaches a standstill. It often highlights themes of frustration and entrapment, making it a powerful narrative device in works that explore human struggles, such as in the works of Samuel Beckett or Harold Pinter.
