Star returned, holding, say, a hot drink (5)
I believe the answer is:
negus
'a hot drink' is the definition.
(I've seen this before)
'star returned holding say' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'returned' is a reversal indicator.
'holding' is an insertion indicator.
'say' becomes 'eg' (both can mean for example).
'sun' reversed gives 'nus'.
'nus' placed around 'eg' is 'NEGUS'.
(Other definitions for negus that I've seen before include "Old Ethiopian king; hot port drink" , "Hot, spiced alcoholic drink" , "Warm drink" , "Hot spiced port drink" , "Ethiopian emperor (hist.)" .)
