Emergent, a new deal (9)
I believe the answer is:
agreement
'deal' is the definition.
(I know that deal can be written as agreement)
'emergent a new' is the wordplay.
'new' indicates an anagram.
'emergent'+'a'='emergenta'
'emergenta' with letters rearranged gives 'AGREEMENT'.
(Other definitions for agreement that I've seen before include "Harmony, concurrence" , "legal contract maybe" , "Compact, accord" , "Accord, contract" , "deal" .)
