Is it just me, or is the room colder than usual?

Yeah, I think the radiator isn't working right.

I noticed that too; I wonder if we should call maintenance.

Good idea! They might need to fix the radiator before winter hits.

Root Explanation

Radiator → It is formed from "radiare" (meaning to emit rays) and the suffix "-tor" (meaning one who or that which). The word "radiator" refers to a device that emits heat or energy, as it radiates warmth into a space.

Memory Tip

Think of a device that 'emits rays' of heat — 'radiator' is all about sending out warmth.
