In literature, the word "until" is used to mark the continuation of an action or state up to a specific moment, event, or condition, thereby creating a sense of suspense or transition. For example, in Wilkie Collins’s work, a character holds a key until Tuesday next ([1]), establishing a clear temporal boundary, while in Dickens’s narratives, actions proceed until a significant turning point is reached, such as waiting at a door until the murky fanlight appears ([2]). Authors often use "until" not only to denote literal time—as in waiting until a meal is served or a person recovers ([3], [4])—but also to signal dramatic or figurative shifts, like a ghost speeding away until it is beyond reach ([5]) or inner visions expanding until they become cosmic ([6]). This versatility in usage allows writers to pace their narratives effectively, creating anticipation and emphasizing the buildup to critical moments.
