Sabotaged hunt okay? Much obliged (5,3)
I believe the answer is:
thank you
'much obliged' is the definition.
(I've seen this before)
'sabotaged hunt okay?' is the wordplay.
'sabotaged' indicates an anagram.
'hunt'+'okay'='huntokay'
'huntokay' is an anagram of 'THANK-YOU'.
(Other definitions for thank you that I've seen before include "Polite reply (to gift)" , "Ta" , "Words of gratitude" , "Words of acknowledgement" , "Cheers" .)
