decelerate
含义: To reduce speed or the rate of progress; to slow down.
Decelerate is the formal antonym of 'accelerate' and is used both literally (vehicles slowing down) and figuratively (economic growth slowing). It is more precise than 'slow down' and is preferred in technical, scientific, and economic writing. Common collocations include 'decelerate sharply,' 'decelerate gradually,' and references to economic growth, inflation, or expansion decelerating.
