How to maintain a career on the road (5)
I believe the answer is:
steer
'how to maintain a' is the definition.
I can't judge whether this definition defines the answer.
'career on the road' is the wordplay.
'career' becomes 'eer' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'the road' becomes 'st'.
'eer' after 'st' is 'STEER'.
Can you help me to learn more?
(Other definitions for steer that I've seen before include "Reset so as to direct" , "bovine creature" , "give guidance" , "Guide (eg, a ship)" , "Cattle - drive" .)
