Morphology

decelerator = decelerate (transparent) = de + celer + ate + or

The noun is a regular agent or causal noun formed from 'decelerate' and means a person or thing that causes slowing.

Etymology

Decelerator uses the same parts de- 'down' and celer 'fast', so it can mean a person or factor that makes a process move more slowly. That's why a rule, cost, or person called a decelerator acts to reduce speed or slow progress, the opposite of an accelerator.
