suddenness
Lack of warning
Suddenness is the quality of happening without warning or preparation.
It captures the abruptness of an event—the way it arrives unexpectedly or all at once: The suddenness of his departure left us stunned.
Where "sudden" describes the event itself, suddenness emphasizes how that quality affects those experiencing it.
