Fubsies skirring into the caliginosity

Harper Collins is running a campaign to save rarely used words from oblivion. Heard about it on on Radio 4. They asking influential cultural figures - humorists, poets, bloggers :) - to use these rare words so Harper Collings have a basis for including them in the next edition of the dictionary. Some of the endangered words, and their definitions on the Merriam Webster (since Harper Collins don't have a free online edition): - skirr: to leave hastily. Webster thinks the etymology may be an alteration of scour. The Radio 4 show suggested onomatopoeia, the sound a bird makes when beating its wings in flight, which sounds more plausible - fubsy: chubby and somewhat squat. I can't believe this beauty actually fell out of usage - Caliginosity: dimness or darkness. Has already vanished from the Webster's, so the link is to the free Wikipedia style dictionary. Radio 4 thinks caliginosity deserves to die. But to me, it evokes a sense of the eerie, an image of a hooded candle flickering in the nave of an enormous cathedral casting shadows into the vast stillness, that mere darkness does not convey. Gloaming feels closer to the mark Harper Collins claim that this exercise is needed because they need to drop words from the dictionary. They need to make room for terms like equity injection and credit crunch by dropping fubsy and skirr. I smell bullshit. Surely, in today's world, the real authoritative version of any dictionary is the soft copy, which is not constrained by size. A physical print edition can be cut to any arbitrary number of words. This seems to be an effort to raise the public profile of rare words. A worthy and noble effort in any circumstances. Lets just drop the bs.
