Shrink from hunting initially with wild boar around (5)
I believe the answer is:
abhor
'shrink from' is the definition.
(to shrink from something is to dislike it)
'hunting initially with wild boar around' is the wordplay.
'initially' indicates taking the first letters.
'with wild boar' becomes 'abor' (I can't justify this - if you can you should give a lot more credence to this answer).
'around' means one lot of letters goes inside another.
The initial letter of 'hunting' is 'h'.
'h' inserted into 'abor' is 'ABHOR'.
Can you help me to learn more?
(Other definitions for abhor that I've seen before include "Regard with repugnance" , "Reject" , "Find disgusting" , "Loathe, detest" , "Regard with disgust and hatred" .)
