Distinguished some of them in entirety (7)
I believe the answer is:
eminent
'distinguished' is the definition.
(synonyms)
'some of them in entirety' is the wordplay.
'some of' says the answer is hidden in the clue.
'EMINENT' can be found hidden inside 'them in entirety'.
(Other definitions for eminent that I've seen before include "Respected; notable" , "High" , "Distinguished, prominent" , "Famous and admired" , "Famous and respected" .)
