Adele ultimately inclined to throttle pub trumpeter (8)
I believe the answer is:
elephant
'trumpeter' is the definition.
(I've seen this before)
'adele ultimately inclined to throttle pub' is the wordplay.
'ultimately' suggests the final letters.
'inclined' becomes 'leant' (I've seen this in another clue).
'to throttle' is an insertion indicator (throttle can mean to strangle or smother).
'pub' becomes 'ph' (abbreviation for Public House).
The last letter of 'adele' is 'e'.
'leant' enclosing 'ph' is 'lephant'.
'e'+'lephant'='ELEPHANT'
(Other definitions for elephant that I've seen before include "Trumpeting animal" , "Huge mammal" , "Large animal (in the room?)" , "Pachyderm hunted for ivory" , "Largest land mammal" .)
