Maybe Leo Delibes’s finale getting poor ratings (4,4)
I believe the answer is:
star sign
'maybe leo' is the definition.
(I know that Leo is a star sign)
'delibes's finale getting poor ratings' is the wordplay.
'finale' suggests the final letters.
'getting' is a charade indicator (letters next to each other).
'poor' is an anagram indicator.
The last letter of 'delibes' is 's'.
'ratings' anagrammed gives 'tarsign'.
's'+'tarsign'='STAR SIGN'
(Other definitions for star sign that I've seen before include "Eg, Leo or Aries" , "Eg, Sagittarius" , "Virgin, for example" , "Leo perhaps" , "Astrological symbol" .)
