Root Explanation

Undiluted → It is formed from "un-" (meaning not) and "dilute" (from Latin "dilutus", meaning to dilute or weaken). The word "undiluted" means not diluted or not weakened, retaining its original strength or concentration.

Memory Tip

Think of 'not' ('un-') weakening something ('dilute') — that's why undiluted means it keeps its full strength.
