Eastern rice gent cooked full of beans (9)
I believe the answer is:
energetic
'full of beans' is the definition.
(thesaurus)
'eastern rice gent cooked' is the wordplay.
'eastern' becomes 'e'.
'cooked' indicates an anagram.
'rice'+'gent'='ricegent'
'ricegent' is an anagram of 'nergetic'.
'e'+'nergetic'='ENERGETIC'
(Other definitions for energetic that I've seen before include "Full of beans" , "Vigorous and dynamic" , "Forceful and with great vitality" , "Forceful, vigorous" , "Lively, spirited" .)
