Cream in some bagel it entered (5)
I believe the answer is:
elite
'cream' is the definition.
(as in the cream of the crop)
'some bagel it entered' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ELITE' is hidden within 'bagel it entered'.
'in' acts as a link.
(Other definitions for elite that I've seen before include "Superior group in society" , "Choice group" , "First-class" , "twelve pitch in the office" , "Select body, cream" .)
