Learner raced off around Victorian highway (6)
I believe the answer is:
calder
'victorian highway' is the definition.
I know nothing about this answer so I can't tell whether this works.
'learner raced off around' is the wordplay.
'learner' becomes 'l'.
'off' indicates an anagram.
'around' means one lot of letters goes inside another.
'raced' with letters rearranged gives 'cader'.
'l' placed inside 'cader' is 'CALDER'.
Can you help me to learn more?
(Another definition for calder that I've seen is " River at Halifax".)
