Root Explanation

Unordered → It is formed from "un-" (meaning not) and "order" (from Old French *ordre*, meaning arrangement or sequence). The word "unordered" means not arranged or lacking a specific sequence.

Memory Tip

Think of 'not' ('un-') having a specific 'arrangement' ('order') — that's why unordered means lacking a specific arrangement.
