The phrasal verb 'wall off' is predominantly used in informal speech and writing, though it can occasionally appear in formal contexts, particularly when discussing architecture, urban planning, or psychological metaphor. It typically means to create a barrier by constructing a wall or division, thereby separating or enclosing a particular area from another space. In physical terms, it might refer to building a wall to divide sections of land or property. Metaphorically, it is often used to describe emotional or mental exclusion or isolation, suggesting someone is blocking off feelings or communication from others. Its versatility in describing both tangible and intangible separations makes it a resourceful choice in varied contexts, although it's more commonly heard in casual conversations than in formal documents or academic discourse. Overall, 'wall off' conjures a sense of isolation or exclusion, whether physical or emotional, depending on the context in which it is used.
