Root Explanation

Unventilated → It is formed from "un-" (meaning not) and "ventilated" (from Latin "ventilare", meaning to fan or to blow). The word "unventilated" means not having air circulation or not being aired out.

Memory Tip

Think of 'not' ('un-') having air blown or circulated ('ventilated') — that's why unventilated means lacking air flow.
