Root Explanation

Preposterously → It is formed from "pre-" (meaning before) and "posterus" (meaning coming after or later). The word describes something that is absurd or contrary to reason, as if the order of things is reversed, with the later coming before the earlier.

Memory Tip

Think of something that is 'before' ('pre-') what should logically come 'after' ('posterus') — that's why preposterously means something absurd or ridiculous.
