I did the Times 6468 earlier this morning and discovered 'urtext ' from Chambers Word Wizard - and then was able to look it up in my NEW Chambers ! ( I don't know how I ever managed without it!)
Yes, Rusty, I gave up the idea of waiting for Christmas! Every time I failed to find an answer, someone always came up with a reply from Chambers , so I decided that was definitely the way to go! My OED (1972 edition)wasn't up to the job any more.
My first introduction to Chambers was from my lovely crossword-mad grandmother. She bought the 1912 edition which I was always asking to borrow.She kept it in her roll-top bureau where it had to placed after use. it is now re-covered (with wallpaper) for the umpteenth time and i treasure it.
