It turns out: Kind of, but not quite.
Since the launch of the new search engine, Cuil.com, (pronounced Cool), on Sunday, it’s been in the news. Well, the nonmainstream news I heed, anyway. One such story was digging deep to discern the truthfulness (or lack thereof) of the site’s claim that cuil is an Irish word that means knowledge.
The results are in: It kind of means that. The word (coll, with a genitive cuill) actually means hazel; it’s associated with wisdom/knowledge in Celtic mythology. This culled from the comments on the above post; the commenter wrote succinctly about it here. So the search engine creators spelled their site wrong, too, apparently.
This is all a side note to whether the search engine actually leads a user to knowledge. From what I’ve heard so far, it’s not scoring too well in that category. When I tried it, I got both tangential results and entirely unrelated results; some results were not even in English. I did not get any directly related results.
