Etymology: "Vection" is a technical coinage rather than an ancient word. It comes from Latin "vectio," a noun meaning a carrying or conveying, which is itself built on "vehere," "to carry." That same root gives English familiar words such as "vehicle," "convey," and "vector," all of which share the idea of something being moved from one place to another. The modern sense is far narrower than its Latin ancestor. Rather than a physical transport of goods or people, the term names the illusion of self-motion that a person perceives when the visual world around them shifts, as when a stationary passenger in a train beside another departing train feels their own carriage gliding. The Latin notion of carrying has been turned inward, so that the body is now the thing being carried, in the perception of the mind.

Synonyms: motion, movement, transportation
