V2 Vocabulary Building Dictionary


verb, noun

Definition: (v.) to weaken or waste away, especially from lack of use; (n.) 1. the weakening, decreasing, or degeneration of a muscle or part of the body; 2. any weakening or degenerative decline

Synonyms: (v.) weaken, degenerate, decline, decay, deteriorate, diminish; (n.) weakening, degeneration

Antonyms: (v.) strengthen, grow; (n.) strengthening, growth

Tips: Atrophy originates from the Latin atrophia, "lack of food," from the Greek trophe, "food" with the "negative" prefix "a." Thus comes the image of atrophying as "wasting away" from lack of food. Also, think of atrophy when muscles shrink from lack of exercise. Atrophy is also related to the noun attrition, which means "a gradual weakening (as a result of continual difficulty or attack.)" For a memory trick, note how atrophy looks and sounds like "a trophy." Now, think about how a trophy is tall and thin. Imagine you ran into an old friend who used to be a tall body builder, but now he is thin, like a trophy. You would say, "I can't believe how much you have atrophied. You now look like a trophy."
