What does zonk mean?
Zonk is an informal word used chiefly as a verb to mean to fall asleep, usually abruptly and soundly. It can mean to doze off during an idle moment, as in “let’s zonk out for a while,” and the related noun names a sleep or nap. Zonk is particularly evocative because it suggests a person who has dropped off completely rather than merely resting. The word appears in casual speech and informal writing, often with a playful or mildly dismissive tone: someone may claim they need to zonk when work feels tedious. Although most common as a verb, zonk can also refer to the sleep itself. Its deliberately blunt sound and its long-standing use in military slang make it more memorable than many ordinary synonyms. It is best suited to informal contexts rather than formal prose.
