Come out and return, eg, again meet half-way (6)
I believe the answer is:
emerge
'come out and' is the definition.
(I've seen this before)
'return eg again meet half-way' is the wordplay.
'return' says the letters should be written backwards.
'again meet half way' becomes 'reme' (I can't explain this - if you can you should give a lot more credence to this answer).
'eg'+'reme'='egreme'
'egreme' back-to-front is 'EMERGE'.
Can you help me to learn more?
(Other definitions for emerge that I've seen before include "Emanate" , "Issue" , "Come into view" , "Come into existence" , "Come out or transpire" .)
