Hi all & Happy New Year.
Have just started learning how to do cryptic crosswords and am working my way through the Times quick cryptic crossword book 1. It being quite an old book, I'm not having much luck tracking down explanations for some of the harder ones, wondered if anyone could enlighten me how the cryptic part of the clue below works? I got it via the definition but can't make the second part work.
Clue: "Everything's ready: eg lass mostly prepared (3,7,2)"
Answer: ALL SYSTEMS GO
Many thanks.
