asativum Say, aren't dictionaries most useful for looking up words you don't already know? So wouldn't a dictionary containing only commonly used words be less useful than one with lots of unfamiliar words?

Telofy Just added them all to dict.cc. They'll stage a superb comeback. Sep 25, 2008
reesetee Appealing to the lowest common denominator, perhaps? Sep 23, 2008
vanishedone Oh, I agree it's a publicity stunt (and yes, I'm helping it along). It's that these aren't ever so obscure that makes it odd, really: you've seen mansuetude and vaticinate, I know apodeictic and compossible from texts that are standard on undergraduate Philosophy courses, and elsewhere people are pointing out that periapt is common in D&D. So what were Collins thinking when they opted for targets that make them look like shoddy researchers whose dictionary would fail to meet undergrads' needs? Sep 22, 2008
yarb This strikes me as a rather pathetic publicity stunt by Collins. I've run into several of these words in recent reading; some (mansuetude, vaticinate) several times.
"Make space"? Very funny.

vanishedone I've seen apodeictic in a recent translation of the Critique of Pure Reason (indeed, the OED definition references Kant), and it's just a variant of apodictic, which is also crucial in Husserl's phenomenology. Someone at Collins doesn't care much about modern philosophy.
Edit: compossible turns up in Leibniz too. This is hardly obscure material. Sep 22, 2008
