Succeed - in understanding the whole thing? (6)
I believe the answer is:
follow
'succeed' is the definition.
(synonyms)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for follow that I've seen before include "Succeed; go after" , "dog" , "Chase" , "Ensue" , "'____ and don't dilly-dally on the way'" .)
