I cheated.
I was supposed to look up this word after defining it with what I know, so feel free to take my pre-definition with a grain of salt.
My initial thought, upon reading the word, was "headed towards death." Mori, I assume, means death, because the words morbid, mortuary, and mourn all have to do with dying. The "bund" part of the word sounds like "bound," so I was thinking, "death bound."
I wasn't too off the mark, but there was another definition I didn't think of: stagnant. I really like that definition.
Because my job is definitely moribund.
