Other forms: chivvied; chivvying
To chivvy is to repeatedly harass or annoy someone. Don't let your little sister chivvy the dog, or she's going to get nipped!
This verb is more commonly used in Britain than the U.S., both to mean "bother," and also "hurry along" or "pursue." So you might chivvy some chickens into their coop or chivvy an opposing player on a soccer field. It was originally chevy, a word etymologists believe derives from the 15th-century Ballad of Chevy Chase, which describes an infamous battle between Scotland and England in the Cheviot Hills.
