She has some leverage (4)
I believe the answer is:
vera
'she' is the definition.
(I've seen this before)
'some leverage' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'VERA' is hidden in the letters of 'leverage'.
'has' acts as a link.
(Other definitions for vera that I've seen before include "Woman's name" , "senior songstress?" , "__ Lynn, the forces' sweetheart" , "Duckworth, Lynn" , "and 15: Singing Dame" .)
