"Up to hilt" is an idiomatic expression used to describe something that is done fully or completely, often exceeding normal or expected levels. The phrase originates from the hilt, which refers to the handle of a sword or dagger. When a blade is inserted into the hilt, it is embedded fully and securely, leaving no part of the blade exposed. Therefore, "up to hilt" figuratively implies that something is being done or carried out to its maximum extent or capacity.
In a literal sense, the phrase can be used to describe a weapon being thrust deeply into an opponent during combat, suggesting a forceful and complete action. However, in a more figurative sense, "up to hilt" is commonly used to emphasize the thoroughness, dedication, or intensity with which a task, effort, or experience is pursued. It implies a total commitment or immersion, leaving no room for half measures or hesitations.
For instance, one might say "He invested up to hilt in the project" to convey that the person put in a significant amount of effort, leaving no stone unturned. Similarly, if someone is enjoying a vacation up to hilt, it means they are fully engrossed in the experience, fully embracing and indulging in every aspect of it.
Overall, "up to hilt" signifies a complete or all-encompassing involvement, emphasizing the extent to which something is pursued or experienced, leaving nothing undone or unexplored.
