Guided around North in advance (4)
I believe the answer is:
lend
'advance' is the definition.
(I know that advance is a more specific form of lend)
'guided around north' is the wordplay.
'guided' becomes 'led' (similar in meaning).
'around' means one lot of letters goes inside another.
'north' becomes 'N' (abbreviation).
'led' enclosing 'n' is 'LEND'.
'in' is the link.
(Other definitions for lend that I've seen before include "Give temporarily" , "contribute" , "Give on condition of return" , "Give the use of for a time" , "Impart" .)
