The phrase “under sentence of execution” borrows the sober diction of formal law to describe the Queen’s casual brutality. The White Rabbit’s secrecy—raising himself on tiptoe, whispering into Alice’s ear—signals a court culture ruled by fear, where news of punishment circulates as a nervous aside rather than open deliberation. His legalistic wording suggests institutional process, yet the chapter shows that the Queen’s “process” is impulse dressed in procedure. Alice’s reply—“What for?”—cuts through the euphemism to the ethical core: cause and justification. The Rabbit’s answer that the Duchess “boxed the Queen’s ears” frames a petty, personal affront as a capital crime, revealing that in Wonderland, offenses against royal dignity eclipse all other measures of harm. The gag that follows—his mishearing “What a pity!”—momentarily pushes Alice toward expected sentimentality; she refuses it, insisting on reasons rather than ritual sympathy. The line therefore announces the chapter’s logic: penalty first, rationale second, with fearful etiquette doing the social work that props up arbitrary power.
