TIME for Dec.10,p 47 uses "fungible" in a way that seems to me the pretentious use of an obscure word when a more common word should have been chosen.

"In Afghanistan, where loyalty is fungible,........."

Here is what WordDectective says about "fungible"

As you can probably gather from that explanation, "fungible" has absolutely nothing to do with
the word "fun," and has no connection to "fungus" despite the involvement of lawyers.
"Fungible" comes from the Latin "fungibilis," which in turn came from the Latin phrase "fungi
vice," meaning "to serve in place of."
