Well the endgame has me completely flummoxed!
I understand from Quisling@2 that it is a pangram, but between not being able to parse extra words in a few clues and not seeing relevant letters in others I am going batty!
For example, the first six rows, if I have the correct words, are 1, (cannot parse), 2, particle, 3, theory, 4, word, 5, pen, 6, ring. Apart from 6 giving possibly 'O' I am at a loss.
Is there a source that will help me out with these and the rest?
