Which of the following is a synonym for 'gaunt'?

The term 'gaunt' refers to someone who is very thin, often as a result of suffering, hunger, or illness. It conveys an image of a person who appears almost skeletal, suggesting a lack of nutrition or health.

'Emaciated' directly captures this meaning, as it describes someone who is abnormally thin or weak, particularly due to malnutrition or illness. Therefore, it aligns perfectly with the connotations of 'gaunt,' making it the most suitable synonym in this context.

The other options, while descriptive in their own right, do not evoke the same imagery as 'gaunt.' 'Plump' suggests fullness or a round shape, 'robust' conveys strength and healthiness, and 'vibrant' implies energy and liveliness—all of which are characteristics contrary to the thin, worn-out impression that 'gaunt' provides. By understanding these distinctions, it becomes clear why 'emaciated' is the best synonym for 'gaunt.'
