Sense: verb/1
'Emaciate' and 'waste away' both describe a person or animal becoming extremely thin, but 'emaciate' is a formal, medical term that often implies visible bones and a critical state, while 'waste away' is the everyday alternative used in conversation and informal writing. 'Atrophy' is more specific — it refers to the shrinking of a particular body part, organ, or muscle from disuse or disease (e.g. 'his leg muscles atrophied after months in a cast'), not the whole body's wasting. 'Skeletonise' is a rare technical term for reducing something to a skeleton, usually describing dead bodies or specimens in forensic or natural-history contexts. For a living person who is dangerously thin due to illness, say 'emaciated' (adjective) in formal writing or 'wasted away' in speech.

Etymology
From Latin 'emaciare' (to make lean), formed from 'ex-' (out, thoroughly) + 'macies' (leanness, thinness). 'Macies' itself comes from 'macer' (thin), which is related to Greek 'makros' (long). The English verb emerged in the early 17th century and has retained its medical/formal register ever since.
