What does roiling mean?
Roiling means churning or bubbling vigorously, as a liquid might when it boils or is disturbed by a strong current. The word is especially evocative for a sea or other body of water whose surface is turbulent and restless. Figuratively, roiling describes intense agitation: emotions may roil within someone, while a crowd or society may be in a state of turmoil. It is stronger than merely being active or unsettled and often suggests a mixture of heat, force, and disorder. Although roiling can describe practical, everyday events, such as water beginning to boil, its vivid sound and imagery also make it common in literary and figurative writing. The related verb “roil” is less common but provides a concise form for the same action.
