Notes on Usage
- "Quay ráo" is a technical compound verb. Its usage is confined to specific industries, primarily sugar manufacturing. It is not used in everyday conversational Vietnamese.
- The verb "quay" alone means "to spin" or "to rotate," and "ráo" means "dry," so the term literally describes the action of "spinning dry."
