I have completed the above but got 5d only because I had the 2 letters from other answers and with that there could only be one answer that fitted. I have since seen the explanation provided in Crossword Solutions but I always thought that the last 4 letters for the clue given minus one of them which is obvious is only a verb and not a noun.
If I am wrong about the sequence of the last 4 letters minus one letter being a verb only and it is a noun then no problem but other views will be appreciated
Thanks
