Fan set out for tie (6)
I believe the answer is:
fasten
'for tie' is the definition.
(I've seen this before)
'fan set out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'fan'+'set'='fanset'
'fanset' with letters rearranged gives 'FASTEN'.
(Other definitions for fasten that I've seen before include "Fix securely" , "Nail" , "Bolt" , "Attach" , "Close, make secure" .)
