Morphology
decelerator = decelerate (transparent) = de + celer + ate + or
The noun is a regular instrument noun formed from the verb 'decelerate' and directly means something that decelerates.
Etymology
Decelerator comes from the parts de- meaning 'down' and celer meaning 'fast'. So a decelerator is a device that pushes speed 'down' and slows movement, the opposite of a car's accelerator.
