* Hill: A raised area of land that is typically smaller than a mountain.
* Mound: A pile of earth, often artificial, like a burial mound or a termite mound.

To figure out what it means specifically, you need more information! Can you tell me more about the situation? For example:
* Where is this lump of land located?
* How big is it?
* What is it used for?
The more information you provide, the better I can help you understand what "lump of land" refers to in your specific context.
