Wife's account of Kerry? bonkers! (5)
I believe the answer is:
wacky
'bonkers' is the definition.
(synonyms)
'wife's account of kerry?' is the wordplay.
'wife' becomes 'w' (abbreviation).
'account' becomes 'ac' (abbreviation for account).
'of kerry?' becomes 'ky' (I can't justify this - if you can you should believe this answer much more).
'w'+'ac'+'ky'='WACKY'
Can you help me to learn more?
(Other definitions for wacky that I've seen before include "Bonkers" , "Funny in a peculiar way" , "Weirdly funny" , "Humorously strange" , "Barmy" .)
