Woman has energy grant adapted for star (9)
I believe the answer is:
pentagram
'for star' is the definition.
(pentagram is a kind of star)
'woman has energy grant adapted' is the wordplay.
'woman' becomes 'pam' ().
'has' is an insertion indicator.
'energy' becomes 'e' (physics symbol as in E=mca).
'adapted' indicates anagramming the letters.
'e'+'grant'='egrant'
'egrant' anagrammed gives 'entagr'.
'pam' going around 'entagr' is 'PENTAGRAM'.
(Other definitions for pentagram that I've seen before include "magical symbol" , "Five-pointed star" , "Five pointed star" , "Mystical symbol" , "Star-shaped figure" .)
