Member some fool I'm badgering (4)
I believe the answer is:
limb
'member' is the definition.
(I know that limb is a type of member)
'some fool i'm badgering' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'LIMB' is hidden in the letters of 'fool im badgering'.
(Other definitions for limb that I've seen before include "Tentacle" , "Branch - arm - leg" , "Branch - member" , "Arm, leg or wing" , "arm, perhaps" .)
