Wild fear that may come to a learner driver (5)
I believe the answer is:
feral
'wild' is the definition.
('feral' can be similar in meaning to 'wild')
'fear that may come to a learner driver' is the wordplay.
'that may come to' indicates an anagram.
'a learner driver' becomes 'l' (I've seen this in other clues).
'fear' with letters rearranged gives 'fera'.
'fera'+'l'='FERAL'
(Other definitions for feral that I've seen before include "'Savage, wild (5)'" , "Escaped-into-wild (animal)" , "beastly" , "Wild and menacing" , "Wild or brutal" .)
