Wild enough to cause fear to a novice? (5)
I believe the answer is:
feral
'wild' is the definition.
('feral' can be similar in meaning to 'wild')
'enough to cause fear to a novice?' is the wordplay.
I cannot quite see how this works, but
'cause' could be 'ra' (Ra is an example) and 'ra' is present in the answer.
'novice?' could be 'l' (abbreviation for Learner e.g. on UK cars) and 'l' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for feral that I've seen before include "Wild or brutal" , "Escaped-into-wild (animal)" , "Flare up, going wild" , "Like a wild animal" , "beastly" .)
