Bit of a fidget, if you follow (3)
I believe the answer is:
get
'follow' is the definition.
(I've seen this in another clue)
'bit of a fidget if' is the wordplay.
'bit of' says the answer is hidden in the clue.
'GET' can be found hidden inside 'fidget if'.
'you' acts as a link.
(Other definitions for get that I've seen before include "Escape" , "Receive; obtain" , "Procure or secure" , "Procure from vegetables" , "Acquire" .)
