In literature, “back” functions as a versatile term that can indicate a return in time, place, or state. It often signals a physical movement toward a previous location, as when a character is described as going back to England ([1]) or retreating into the shadows ([2]), and it can also denote a reversal or undoing of action, such as being sent back empty-handed ([3]) or having one’s self-composure restored ([4]). Moreover, “back” is used to mark spatial relationships and positions—whether referring to a specific part of a building like a back-parlour ([5], [6]), or evoking the human body itself ([7]). In its many capacities, the term enriches narrative texture by conveying both literal direction and layers of metaphorical meaning ([8], [9]).
