1.
corner, nook, out-of-the-way spot
A small, tucked-away corner or section of a larger space. Often implies a quiet, inconspicuous, or marginal location. Used both literally for physical spaces and figuratively for peripheral areas of larger domains.
Usage
Often preceded by a location + の: 部屋の片隅 (a corner of the room), 街の片隅 (a corner of the city). Carries a nuance of being small, quiet, or overlooked, unlike 角 (a geometric corner) or 隅 (a corner of a room). The phrase 世界の片隅 (a corner of the world) was popularized by the animated film of the same title.
