Acclaim some rising digital celebrities (5)
I believe the answer is:
eclat
'acclaim' is the definition.
(synonyms)
'some rising digital celebrities' is the wordplay.
'rising' is a reversal indicator (in a down clue, letters go up).
'some' indicates a hidden word (some parts of the word are used).
'talce' is hidden in the letters of 'digital celebrities'.
'talce' written backwards gives 'ECLAT'.
(Other definitions for eclat that I've seen before include "Brilliant success - striking effect" , "Splash" , "Showy effect (Fr.)" , "Conspicuous success or distinction - in France" , "Distinguished success" .)
