Which word means to delay or put off for later?

The term "procrastinate" specifically refers to the act of delaying or postponing tasks or activities. It often implies putting off responsibilities or decisions, usually to a later time, often due to a lack of motivation or prioritization. Procrastination is a common behavior that many encounter in various aspects of life, particularly when faced with tasks that might be unappealing or overwhelming.

In contrast, the other words have distinct meanings that do not align with the concept of delay. "Pry" refers to inquisitively or intrusively trying to discover information, "quaff" relates to drinking something deeply and often quickly, particularly an alcoholic beverage, and "quack" can mean either a fraudulent practitioner of medicine or to make a sound like a duck. Thus, the clarity and alignment of "procrastinate" with the concept of delaying make it the right choice in this context.
