Fast vs. Quick: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on November 6, 2023
"Fast" refers to sustained speed over time, while "quick" denotes brief, immediate speed or action.
Key Differences
Both "fast" and "quick" pertain to speed, but their uses often differ in context. While "fast" usually describes a consistent speed over a duration, "quick" often refers to a brief or immediate action.
If someone is a "fast runner," they can maintain a high speed over a considerable distance. On the other hand, a "quick glance" is momentary, implying it happened in a short span.
"Fast" can also describe the absence of movement, as in "holding fast" or "fast asleep," indicating a firmness or deepness. In contrast, "quick" can pertain to liveliness or responsiveness, as in "quick reflexes" or a "quick wit."
When referring to time, "fast" might suggest a longer duration of speed, like "The day went by fast." "Quick," however, might refer to immediacy, such as in the phrase "in a quick minute."
In some cases, the two words can be interchangeable without drastically altering the meaning, but subtle nuances can still exist. For instance, "fast response" might imply efficiency, while "quick response" emphasizes immediacy.
