Pointless accepting stench - horrible (8)
I believe the answer is:
inhumane
'horrible' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'pointless accepting stench' is the wordplay.
'pointless' becomes 'inane' (I've seen this in another clue).
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'stench' becomes 'hum' (I've seen this before).
'inane' placed around 'hum' is 'INHUMANE'.
Can you help me to learn more?
(Other definitions for inhumane that I've seen before include "Callous" , "Heartless" , "Not compassionate" , "Cruel" .)
