Admirers cherish grand feature of Dracula (5)
I believe the answer is:
fangs
'feature of dracula' is the definition.
(Dracula has fangs)
'admirers cherish grand' is the wordplay.
'admirers' becomes 'fans' (fan is a kind of admirer).
'cherish' indicates putting letters inside (inserted letters are held or cherished by others).
'grand' becomes 'g' (G is short for grand as in a thousand).
'fans' going around 'g' is 'FANGS'.
(Other definitions for fangs that I've seen before include "Large pointed teeth" , "Teeth of, say, wolf" .)
