treasure and trove
This trove goes beyond typical codependent words such as the pomp in pomp and circumstance.
Webster's New World demonstrates why trove is the ultimate second-class citizen of the word world. Not only is it attached to treasure with a hyphen -- treasure-trove -- but it doesn't even retain its own definition. Of trove, Webster's says only, "short for treasure-trove." As such, it's barely clinging to life.
I say we put it out of its misery.
