Hateful male I arrest is hiding in a trunk (10)
I believe the answer is:
abominable
'hateful' is the definition.
('abominable' can be similar in meaning to 'hateful')
'male i arrest is hiding in a trunk' is the wordplay.
'male' becomes 'm' (common abbreviation).
'arrest' becomes 'nab' ('nab' can be a synonym of 'arrest'**).
'is hiding in' indicates putting letters inside.
'trunk' becomes 'bole' (I've seen this in other clues).
'm'+'i'+'nab'='minab'
'a'+'bole'='abole'
'minab' put into 'abole' is 'ABOMINABLE'.
(Other definitions for abominable that I've seen before include "Very bad, terrible" , "Hateful" , "Odious" , "Atrocious" , "Causing moral revulsion" .)
