to and fro
Alternating directional movement
To and fro describes movement back and forth between two points or in alternating directions.
The phrase functions as both adverb and adjective: She paced to and fro while waiting for news; the to-and-fro motion of the pendulum.
It suggests repetitive, often restless movement without significant progress in either direction.
The noun form, usually hyphenated as to-and-fro, refers to such movement itself or to ongoing exchange: the to-and-fro of political debate.
