Atrophy is a noun that refers to a wasting away. It can also serve as a verb that means ‘to waste away.’
The literal translation of our word of the day, from the Greeks is ‘lack of nourishment.’ But in more recent years, atrophy often takes on a more metaphorical meaning that has nothing to do with actual food. A person’s muscles can atrophy if they haven’t been used for a while and the same can happen to job skills that have been dormant.
As a kid I spoke fluent Italian. But it’s been so long since I’ve spoken any of the language that my Italian has atrophied a great deal.
