Send cider - terribly distinguished (9)
I believe the answer is:
discerned
'distinguished' is the definition.
('discern' can be a synonym of 'distinguish')
'send cider terribly' is the wordplay.
'terribly' indicates anagramming the letters.
'send'+'cider'='sendcider'
'sendcider' anagrammed gives 'DISCERNED'.
(Other definitions for discerned that I've seen before include "Caught sight of" , "Identified by close investigation" , "Distinguished, made out" .)
