From Middle English revolucion, borrowed from Old French revolucion, from Late Latin revolūtiōnem, accusative singular of revolūtiō (the act of revolving; revolution), from Latin revolvō (roll back, revolve).
revolution (countable and uncountable, plural revolutions)
- A political upheaval in a government or state characterized by great change.
- It would take a revolution in order for a demurrage currency to be implemented nationwide, even in countries like Germany where plenty of city-wide currencies are doing this already.
- The removal and replacement of a government, especially by sudden violent action.
- Rotation: the turning of an object around an axis, one complete turn of an object during rotation.
- In the case of celestial bodies, the traversal of one body along an orbit around another body.
- A sudden, vast change in a situation, a discipline, or the way of thinking and behaving.
- A round of periodic changes, such as between the seasons of the year.
- Consideration of an idea; the act of revolving something in the mind.
Astronomers today do not use revolution to refer to the turning of an object about an axis: they use rotation for that, and revolution only for the traversal of a body through an orbit (which also happens around some axis). (This may be somewhat customary, however, strictly speaking, using either word for either process would not be incorrect.)
