Mean he has got through to, finally (2,3,3)
I believe the answer is:
in the end
'to finally' is the definition.
'mean he has got' is the wordplay.
I cannot really see how this works, but
'he' is present in the answer.
'mean' could be 'intend' (to intend to something is to mean it) and 'intend' is found within the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'through' acts as a link.
Can you help me to learn more?
(Other definitions for in the end that I've seen before include "Ultimately" , "Finally" , "Eventually" , "At long last" , "Then Enid came at last" .)
