The remaining ones we're told to pull off (5)
I believe the answer is:
wrest
'pull off' is the definition.
'wrest' can be an answer for 'pull' (thesaurus). I'm not certain of the 'off' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for wrest that I've seen before include "Forcibly pull (something from someone's grip)" , "Forcibly pull away" , "Seize by forceful means" , "Strew (anag.)" , "Take away forcibly" .)
