Wasted old husband starting to argue for nothing — thrown out (9)
I believe the answer is:
exhausted
'wasted' is the definition.
(thesaurus)
'old husband starting to argue for nothing thrown out' is the wordplay.
I cannot really understand how this works, but
'old' could be 'ex' and 'ex' is present in the answer.
'husband' could be 'h' and 'h' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for exhausted that I've seen before include "Worn out" , "Dead-beat" , "All in, really tired" , "Drained of strength" , "spent" .)
