In literature, the word "enter" functions both as a literal instruction and a rich metaphorical device, reflecting the fluid movement between spaces, states, or conditions. In dramatic texts, it frequently serves as a stage direction to introduce characters—consider Shakespeare’s succinct calls such as “Enter Edgar” ([1]) or “Enter Romeo” ([2]), which signal shifts in action and mood. Meanwhile, in narrative and philosophical texts, "enter" conveys transitions into new realms or ideas, as seen when a character claims a right to "enter Paradise" ([3]) or when abstract concepts are said to "enter into the memory" ([4]). Even in non-dramatic contexts, the term is used to denote physical movement into a space—be it a gate leading into a palace ([5]), the act of logging into a system ([6]), or instructions guiding social behavior ([7]). Overall, "enter" serves as a versatile tool in literature to guide both the audience’s understanding of spatial movement and the symbolic journey from one state of existence to another.
