Applauded on leaving, exhausted (7,3)
I believe the answer is:
clapped out
'exhausted' is the definition.
(I've seen this before)
'applauded on leaving' is the wordplay.
'applauded' becomes 'clapped' ('clap' can be a synonym of 'applaud').
'on leaving' becomes 'out' (I can't justify this - if you can you should give a lot more credence to this answer).
'clapped'+'out'='CLAPPED-OUT'
Can you help me to learn more?
(Other definitions for clapped out that I've seen before include "Exhausted" , "Dilapidated" , "Finished" , "so given a hand when leaving?" , "too many curtain calls?" .)
