At Language Log (which in Japan would be a national treasure or kokuhō), Geoffrey Pullum gingerly enters a row between linguists over the intrinsic value of language diversity. He cites
the survival of an isolated southern Alaskan tribal language [Eyak], with its precious word demexch for a dangerously thin spot on the ice.
I propose to conscript this word forthwith into English. Can John McCain cross his campaign finance/Isegirl demexch?
Current Google hits for demexch: 121. But they are citations. I claim priority in use.
