Root Explanation

Presumption → It is formed from "pre-" (meaning before) and "sumere" (meaning to take). The word refers to taking something for granted or assuming something beforehand.

Memory Tip

Think of 'taking' ('sumere') something 'before' ('pre-') it is proven — that's why presumption means assuming something in advance.
