Present in smithereens (5)
I believe the answer is:
there
'present' is the definition.
(I've seen this before)
'in smithereens' is the wordplay.
'in' says the answer is hidden in the clue.
'THERE' is hidden within 'smithereens'.
(Other definitions for there that I've seen before include "Consoling word" , "comforting word" , "Thither" , "that particular place" , "In position" .)
