n. the quality or state of being rapid; swiftness
rapidity = rapid<fast> + ity<noun suffix>
- rapid (from Latin rapidus, meaning "swift, quick")
- ity (noun-forming suffix from Latin -itas, indicating a state or condition)
Etymology Origin:
The word "rapidity" originates from the Latin rapidus (swift), derived from rapere (to seize or carry off). The suffix -ity was added in Middle English via Old French to form an abstract noun denoting the quality of speed. The evolution reflects a logical progression from the action of seizing (implying quick movement) to the abstract concept of swiftness.
