Describe energy policy during appointment (9)
I believe the answer is:
delineate
'describe' is the definition.
(delineating is a kind of describing)
'energy policy during appointment' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mc2).
'policy' becomes 'line' (the party line is a party's policy on something).
'during' indicates putting letters inside.
'appointment' becomes 'date' (synonyms).
'e'+'line'='eline'
'eline' put inside 'date' is 'DELINEATE'.
(Other definitions for delineate that I've seen before include "Portray precisely - teen ideal (anag)" , "Trace" , "Precisely describe" , "Draw" , "Outline" .)
