What does the term "quaff" mean?

The term "quaff" specifically means to drink heartily or with enjoyment. It often implies that the drink is consumed in a large volume and typically refers to beverages that are refreshing or celebratory, like ale or cider. This word emphasizes the act of drinking in a manner that suggests pleasure or indifference to excess, which is why this definition captures the essence of the word most accurately.

The other choices focus on different actions that do not align with the meaning of "quaff." Eating quickly is a separate action that relates to food consumption, while smelling something involves the sense of smell and has no relation to drinking. Digesting food is a physiological process and does not pertain to the act of drinking at all. Thus, the correct answer highlights the specific action associated with "quaff."
