Stars ultimately fuming about a complaint by listener (5,4)
I believe the answer is:
great bear
'stars' is the definition.
(constellation Ursa Major)
'ultimately fuming about a complaint by listener' is the wordplay.
'ultimately' indicates one should take the final letters.
'about' becomes 're' ('re' means regarding or about).
'complaint by' becomes 'tb' (I can't explain this - if you can you should give a lot more credence to this answer).
'listener' becomes 'ear' (body part which hears or listens).
The final letter of 'fuming' is 'g'.
'g'+'re'+'a'+'tb'+'ear'='GREAT BEAR'
Can you help me to learn more?
(Other definitions for great bear that I've seen before include "Ursa Major" , "Major stars" , "'Large ursine in the heavens (5,4)'" , "Large animal - same as 7" , "visible in the night sky" .)
