What does it mean to be hidden while waiting in ambush?

Being hidden while waiting in ambush refers to the act of concealing oneself in preparation for an unexpected attack or confrontation. This strategy is essential in tactics where surprise is a critical element for success. The term "lurking" accurately captures this concept, as it implies remaining out of sight and waiting in a concealed position, often with the intent to spring into action unexpectedly.

The other terms do not convey the same meaning. "Harrow" is associated with distress or to cause anguish rather than hiding. "Desist" means to stop or refrain from action, which contrasts with the proactive stance of ambushing. "Sparse" typically describes something that is thinly scattered or distributed, which does not relate to the idea of hiding or ambushing at all. Understanding the context of these terms reinforces why "lurking" is the most fitting choice for describing the act of being hidden while waiting to ambush.
