Many move up, being bright (6)
I believe the answer is:
clever
'bright' is the definition.
(bright can mean clever or intelligent)
'many move up being' is the wordplay.
I cannot quite understand how this works, but
'many' could be 'l' and 'l' is located in the answer.
'being' could be 'eve' (Eve is an example) and 'eve' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for clever that I've seen before include "Smart and ingenious" , "Quick at learning and understanding" , "Brainy, smart" , "Mentally or physically skilful" , "Quick at learning, bright" .)
