Root Explanation

Insulated → It is formed from "in-" (meaning not) and "salare" (from Latin, meaning to salt). The word originally referred to something that is not salted, but in modern usage, it describes something that is protected or separated from outside influences, particularly in terms of heat or electricity.

Memory Tip

Think of something that is 'not' ('in-') exposed to outside elements, like heat or cold, which helps you remember that 'insulated' means protected from outside influences.
