Which term reflects a lack of definitive planning or purpose?

The term that reflects a lack of definitive planning or purpose is "desultory." This word is often used to describe actions or thought processes that are random, disconnected, or lacking a coherent plan. When something is desultory, it suggests an absence of direction, where effort or attention does not follow a clear path or established goals, making it seem haphazard or aimless.

In contrast, "dilatory" refers to a tendency to delay or procrastinate, which implies a deliberate choice to postpone actions rather than an absence of planning. "Depredate" relates to the act of plundering or robbing, focusing on destructive actions rather than lack of plan. "Voracious" describes an insatiable appetite or eagerness, which does not address the concept of planning or purpose at all. Thus, "desultory" stands out as the most fitting term for conveying a lack of definitive planning or purpose.
