Beginning to develop new way to go up in the world (7)
I believe the answer is:
nascent
'beginning to develop' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nascent that I've seen before include "not yet mature" , "Starting existence" , "Coming alive" , "starting to happen" , "being coined" .)
