Doctor reunited with Newton leaving full of knowledge (7)
I believe the answer is:
erudite
'full of knowledge' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for erudite that I've seen before include "Rude tie (anag.)" , "Having or showing great knowledge or learning" , "Showing profound knowledge" , "Learned and scholarly" , "Possessing great learning" .)
