Root Explanation

**Peneplain** → The word is formed from "pene-" (from Latin *paene*, meaning almost) and "plain" (from Old French *plain*, meaning flat or level). A peneplain refers to a nearly flat land surface that has been eroded to a level close to base level, but not completely flat.

Memory Tip

Think of 'almost' ('pene-') flat ('plain') to remember that a peneplain is a land surface that is nearly flat.
