Road from outskirts of Stockport lined with oak, perhaps (6)
I believe the answer is:
street
'road' is the definition.
(street is a kind of road)
'outskirts of stockport lined with oak perhaps' is the wordplay.
'outskirts of' suggests removing the centre.
'lined with' means one lot of letters goes inside another (I've seen this in other clues).
'oak perhaps' becomes 'tree' (oak is a kind of tree).
'stockport' with its middle removed is 'st'.
'st' enclosing 'tree' is 'STREET'.
'from' acts as a link.
(Other definitions for street that I've seen before include "Thoroughfare lined with buildings" , "Paved road" , "Perry's Della" , "City road" , "Town thoroughfare" .)
