English get nicer stews full of beans (9)
I believe the answer is:
energetic
'full of beans' is the definition.
(full of beans can informally mean full of energy)
'english get nicer stews' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'stews' indicates anagramming the letters.
'get'+'nicer'='getnicer'
'getnicer' is an anagram of 'nergetic'.
'e'+'nergetic'='ENERGETIC'
(Other definitions for energetic that I've seen before include "It's vital" , "Forceful, vigorous" , "Lively, spirited" , "Involving great activity" , "High-powered" .)
