Coveted new energy arising from struggle with director (6)
I believe the answer is:
envied
'coveted new' is the definition.
'envied' can be an answer for 'coveted' (I've seen this in another clue). I am unsure of the 'new' bit.
'energy arising from struggle with director' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mc2).
'arising from' becomes 'n' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'struggle' becomes 'vie' (to vie is to struggle or contend with).
'with' says to put letters next to each other.
'director' becomes 'd' (abbreviation eg in film reviews).
'e'+'n'+'vie'+'d'='ENVIED'
Can you help me to learn more?
(Other definitions for envied that I've seen before include "Was jealous of (someone)" , "Desired" , "Was jealous of, begrudged" , "Begrudged, coveted" , "Looked greenly" .)
