Conversation

Have you heard about the new airshed project in our city?

No, I haven't! What is it all about?

It's designed to improve air quality by creating a specific airshed for cleaner air.

That sounds interesting! I hope it actually makes a difference.

Root Explanation

Airshed → The word is formed from "air" (from Old English "aer", meaning the invisible gaseous substance surrounding the Earth) and "shed" (from Old English "scead", meaning to divide or separate). An airshed refers to a region of air that is separated from other regions, often used in environmental contexts to describe areas affected by air pollution.

Memory Tip

Imagine a specific area of 'air' that is 'divided' or 'separated' from others — that's what an airshed is, a defined space of air.
