Did you hear about the new defibrillator they installed at the gym?

Yeah, I think it's a great safety measure for everyone who works out there.

Root Explanation

Defibrillator → It is formed from "de-" (meaning down or away) and "fibrilla" (from Latin *fibrilla*, meaning a small fiber) and "-tor" (meaning one who). The word refers to a device that removes or reduces the fibrillation of the heart, effectively restoring normal rhythm.

Memory Tip

Think of 'removing' ('de-') the 'small fibers' ('fibrilla') of the heart's irregular rhythm — that's what a defibrillator does.
