To waste away in flesh, to make abnormally lean. Often used as a verbal adjective, as in After his diet, he looked emaciated.
It never entered his head to analyse the details of the sick man’s situation, to consider how that body was lying under the quilt, how those emaciated legs and thighs and spine were lying huddled up, and whether they could not be made more comfortable, whether anything could not be done to make things, if not better, at least less bad. It made his blood run cold when he began to think of all these details.
—Leo Tolstoy Anna Karenin (1877)
