Acarpous is an adjective that means sterile or not producing fruit.
Karpos (CAR pose) is the Greek word for fruit. The addition of the prefix A turns it into ‘fruitless.’ Our word of the day may refer to actual food but it may be used to mean any living creature that produces no offspring. It may also be used metaphorically to mean ‘unproductive’ or ‘futile.’ For example: The purpose of the meeting was to generate new ideas for the spring sale, but we couldn’t think of any. I had no idea the meeting would turn out to be so acarpous.
