Object about reckless and humiliating defeat (9)
I believe the answer is:
thrashing
'humiliating defeat' is the definition.
'thrashing' can be an answer for 'defeat' (thrashing is a kind of defeat). I am not sure about the 'humiliating' bit.
'object about reckless' is the wordplay.
'object' becomes 'thing' (an object is a thing or item).
'about' means one lot of letters goes inside another.
'reckless' becomes 'rash' (synonyms).
'thing' enclosing 'rash' is 'THRASHING'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for thrashing that I've seen before include "A very heady defeat" , "Hiding" , "punishment" , "beating" .)
