Doldrums is a noun that refers to a slump or a state of stagnation.
The exact etymology of our word of the day is unknown, but we know it was first used as a nautical term to describe periods of time without strong winds — which was a problem for sailing vessels.
Today, the word is used in a similar way to describe periods of stagnation or the absence of inspiration.
