Ruled type out, so they say (9)
I believe the answer is:
reputedly
'so they say' is the definition.
'ruled type out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'ruled'+'type'='ruledtype'
'ruledtype' with letters rearranged gives 'REPUTEDLY'.
(Other definitions for reputedly that I've seen before include "according to general belief" , "presumably" , "Allegedly" , "alleged" .)
