Moribund
Approaching death; dying.
I came across moribund in Thomas Cleary’s introduction to the Shambhala edition of The Art Of War. I’ve picked up the meaning by context and realized I had only the vaguest sense of its actual meaning. In usage it describes dysfunctional organizations, dull speakers, and political careers after a scandal. The more I thought about it, the more I realized that I didn’t really know what it meant beyond it being a word associated with failure. Of course, that’s what dictionaries are for.
