The term "skeletonlike" refers to something that is thin, bony, and lacking in flesh or substance. Its antonyms could be "plump," "chubby," "well-nourished," "fleshy," or "robust." Whereas "skeletonlike" invokes an image of frailty, its antonyms evoke a sense of vitality and health. These antonyms suggest not only a physical state but also a mental and emotional well-being. "Plump" implies a sense of happiness and contentment, while "robust" suggests strength and resilience. Therefore, when we describe something as "skeletonlike," we imply that it is weak and feeble, but when we use its antonyms, we convey a sense of vibrant and energetic life.
