What does zonked mean?
Zonked is an informal adjective for being extremely tired, exhausted, or so sleepy that ordinary activity becomes difficult. It is especially natural after prolonged exertion, a long journey, or a night of poor sleep: “I was zonked by the time we got home.” The word can also convey a dazed or heavily affected state, particularly in informal descriptions of alcohol or drugs. Zonked is more expressive than simply tired and often suggests a temporary condition that sleep will remedy. It belongs primarily to informal speech and writing rather than formal prose, though its meaning is widely understood. In everyday conversation, “zonked” is useful because it turns ordinary fatigue into vivid, instantly recognizable shorthand.
