Fast vs. Quickly
What's the Difference?
Fast and quickly are often used interchangeably to describe something happening at a high speed or in a short amount of time. However, there is a subtle difference between the two. Fast typically refers to the rate at which something is moving or happening, while quickly refers to the speed at which something is done or completed. For example, a car may be fast on the highway, but a person may quickly finish a task. Ultimately, both words convey a sense of speed and efficiency, but the context in which they are used can determine their specific meaning.
