What word describes the mesa?

The word that describes a mesa is mesa itself! It's the Spanish word for "table", which accurately describes the flat-topped, steep-sided hill or mountain.

However, if you're looking for a more descriptive term, you could also use:

* Butte: A smaller, more isolated mesa.

* Tableland: A broader term that refers to any flat-topped landform, including plateaus.

* Plateau: A large, flat area of land elevated above surrounding areas.

* Flat-topped hill: A more generic term that describes the mesa's shape.

The best word to use will depend on the specific context and what you want to emphasize.
