A Compendium of Lost Words? How delightful.
One wonders, if lost, how they came by them. Perhaps they weren't lost at all, perhaps they were taken. Then, years later, when no-one is using them (and how could they use them, since they were taken?), up pops the Compendium to show what we have lost. Brilliant ruse. Shame they didn't open a small building society account with a couple of groats at the same time - imagine what that would be with interest.
Anyway, I took a look, and rapidly realised why these words are lost. They weren't taken, they weren't lost, they were thrown away because they were all bloody hard. And because they rolled off the tongue like a piece of blotting paper.
For example: crocitation (1623 -1656)
The crocitation of the gulls meant that I got no sleep last night.See what I mean? Blotting paper. Damn, they should have been lost at sea.
