New way up emerging (7)
I believe the answer is:
nascent
'emerging' is the definition.
('nascent' can be a synonym of 'emerging')
'new way up' is the wordplay.
'new' becomes 'n'.
'way up' becomes 'ascent' (I've seen this before).
'n'+'ascent'='NASCENT'
(Other definitions for nascent that I've seen before include "Incipient" , "Budding early" , "coming into circulation?" , "Newly-formed" , "Starting to grow" .)
