/ˌdiːseləˈreɪʃn//ˌdiːseləˈreɪʃn/

The word "deceleration" has its roots in Latin. The prefix "de-" means "down" or "away from," and the root "celerare" means "to hasten" or "to speed." Together, the word "deceleration" literally means "to become slower" or "to lose speed." The word "deceleration" was first used in the 17th century in the context of physics, particularly in relation to the slowing down of moving objects. It was later adopted in other fields, such as medicine, to describe a reduction in the rate of a biological process, and in economics, to describe a decline in economic activity. Over time, the word "deceleration" has become a standard term in various scientific and technical fields, and is widely used today to describe any situation in which the speed or rate of something is decreasing.
