Way someone good hugs oak? (6)
I believe the answer is:
street
'way' is the definition.
(I know that street is a type of thoroughfare)
'someone good hugs oak?' is the wordplay.
'someone good' becomes 'st' (saint).
'hugs' indicates putting letters inside.
'oak?' becomes 'tree' (oak is a kind of tree).
'st' going around 'tree' is 'STREET'.
(Other definitions for street that I've seen before include "lane" , "Urban thoroughfare" , "Form of theatre" , "Thoroughfare lined with buildings" , "Way < in which common man is" .)
