The basic support or foundation needed for something to happen or be built upon.

Groundwork is formed from "ground" (from Old English "grund", meaning the surface of the earth or land) and "work" (from Old English "weorc", meaning activity or effort). The term refers to the foundational work or preparation laid down for a project or task.
Think of the 'surface of the earth' ('ground') where you lay down the 'effort' ('work') needed to build something. This helps you remember that groundwork is the essential preparation for any undertaking.
