In support of apprentice officially receiving pardon? (6)
I believe the answer is:
behind
'in support of' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for behind that I've seen before include "support" , "Hidden by; bottom" , "in van? No" , "At the back of" , "Taking place in secret" .)
