Root Explanation

Presupposition → It is formed from "pre-" (meaning before) and "suppositio" (from Latin, meaning to place under or assume). The word refers to an assumption made beforehand, something that is taken for granted before further discussion or analysis.

Memory Tip

Think of making an assumption 'before' ('pre-') something is discussed or analyzed — that's what presupposition means.
