speed

velocity / rate of motion / accelerate / hasten / drive fast

/spiːd/

Transitive VerbIntransitive Verb[C/U] Both
past: spedpp: speding: speeding

The word evokes a sense of rapid motion or the acceleration of a process. In its noun form, it is often neutral and technical, focusing on measurement and capability. As a verb, "speed" carries two distinct energies: one of efficiency (causing something to happen faster) and one of urgency or recklessness (moving too fast). When used intransitively regarding travel, it often implies a certain thrill or danger, frequently associated with breaking laws or pushing limits. This contrasts with the transitive use, which is more common in professional or scientific contexts like "speeding up production" or "speeding recovery."

Uncountable when discussing the general physical concept of velocity ('Speed is distance divided by time'). Countable when referring to a specific measurement or record on a speedometer ('The car hit several high speeds during the test').

Over time, the meaning shifted from the general concept of progress to the specific physical measurement of velocity and the act of moving rapidly.
