No promises broken in garbled statement (10)
I believe the answer is:
spoonerism
'garbled statement' is the definition.
'spoonerism' can be an answer for 'statement' (spoonerism is a kind of statement). I am not sure about the 'garbled' bit.
'no promises broken' is the wordplay.
'broken' is an anagram indicator.
'no'+'promises'='nopromises'
'nopromises' with letters rearranged gives 'SPOONERISM'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for spoonerism that I've seen before include ""A lopping of sweaters", for example" , "Burly chassis for Shirley Bassey, say?" , "Verbal exchange of leading characters" , "A slip of the tongue? -- no promises (anag)" , "Regular announcement by old clergyman" .)
