He speeds round in awfully hard turn northward (7)
I believe the answer is:
roadhog
'he speeds' is the definition.
(reckless or speedy driver)
'round in awfully hard turn northward' is the wordplay.
'round in awfully' becomes 'road' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'turn' becomes 'go' (a person's move in a board game).
'northward' is a reversal indicator (in down clue going up).
'go' reversed gives 'og'.
'road'+'h'+'og'='ROADHOG'
Can you help me to learn more?
(Another definition for roadhog that I've seen is " Reckless driver".)
