Entailed ref being wrong but respectful (11)
I believe the answer is:
deferential
'respectful' is the definition.
(similar in meaning)
'entailed ref being wrong' is the wordplay.
'being wrong' indicates anagramming the letters.
'entailed'+'ref'='entailedref'
'entailedref' anagrammed gives 'DEFERENTIAL'.
'but' acts as a link.
(Other definitions for deferential that I've seen before include "Respectful" , "Showing respect" , "Submissive" .)
