Way one's embraced by staff (4)
I believe the answer is:
road
'way' is the definition.
(road is a kind of way)
'one's embraced by staff' is the wordplay.
'one' becomes 'a'.
'embraced by' means one lot of letters goes inside another.
'staff' becomes 'rod' (I've seen this before).
'a' inserted inside 'rod' is 'ROAD'.
(Other definitions for road that I've seen before include "public highway" , "Street" , "motorway?" , "Way to achieving a particular outcome" , "mine gallery" .)
