Anthony Claden sent in a link to Wade Davis, "The World Until Yesterday by Jared Diamond – review", The Guardian 1/9/2013:
In not one of the hundreds of Aboriginal dialects and languages was there a word for time.
For some comments about time-reference in an Australian language, see "Journalistic dreamtime" (3/8/2007); for some generally relevant discussion, see Stan Carey, "Amondawa has no word for ‘time’?", Sentence First 5/21/2011.
And James Eagle sent in this one — Wade Davis, Into the Silence: The Great War, Mallory, and the Conquest of Everest, 2011:
In Tibetan, there is no word for a mountain summit; the very place the British so avidly sought, their highest goal, did not even exist in the language of their Sherpa porters.
James observes that
His claim that "no word for"="does not exist in the language" would be rather silly even if he hadn't accidentally refuted it in the *very same sentence* by highlighting that English has no word for "mountain summit" either…
So this post is duly added to the "'No word for X' archive".
