1
high speed of movement or action
The state of happening or moving very fast.
사용 패턴：
the rapidity of [something]
자주 하는 실수：
Learners sometimes use *rapidity* where *rapid* or *fast* is correct. *Rapidity* is a noun, so say "the rapidity of the train" or "its rapidity," not "the train is rapidity." Learners also often forget the article and preposition: the natural pattern is "the rapidity of [something]."

2
quickness of thought or reaction
The state of thinking or answering very fast.
사용 패턴：
the rapidity of [someone’s] [thought/response]
자주 하는 실수：
Learners may confuse this sense with physical speed. When used with words like "thought," "response," or "decision," it refers to mental quickness, not movement. They also sometimes say "a rapidity answer" instead of "the rapidity of her answer"; remember that *rapidity* is a noun and needs a structure like "the rapidity of [something]."

|
swiftness (Formal word for speed; can be used for actions or decisions, not only thoughts.)
반의어
sluggishness (Suggests slow, heavy, or lazy thinking or reaction.)
|
slowness (General opposite, focusing on low speed of thought or response.)
