Please. With the help given I am now wrong for 22D Cross-dressing is a bore ?R?? (I had this as an anagram of bore which was robe, I haven't a clue now). Thank you.
It just means a word in a cryptic clue that tells you to anagram certain elements - such as around, about, new, somehow, roundabout, messy etc etc! If there's not one there, there can't be an anagram involved.
