Detestable, sending bear north (9)
I believe the answer is:
abhorrent
'detestable' is the definition.
(synonyms)
'sending bear north' is the wordplay.
'sending' indicates an anagram (letters are sent to different positions).
'bear'+'north'='bearnorth'
'bearnorth' anagrammed gives 'ABHORRENT'.
(Other definitions for abhorrent that I've seen before include "noisome" , "execrable" , "Repugnant, detestable" , "Repugnant, offensive" , "Inspiring disgust and loathing" .)
