If you believe account, my racket got smashed (9,2)
I believe the answer is:
according to
'if you believe' is the definition.
I can't tell whether this defines the answer.
'account my racket got smashed' is the wordplay.
'account' becomes 'ac' (abbreviation).
'my' becomes 'cor' (both are expressions of surprise).
'racket' becomes 'din' (both can mean a loud noise or disturbance).
'smashed' is an anagram indicator.
'got' anagrammed gives 'gto'.
'ac'+'cor'+'din'+'gto'='ACCORDING TO'
Can you help me to learn more?
(Another definition for according to that I've seen is " As stated by".)
