At body of water in the midlands, they come together and resurface (8)
I believe the answer is:
reemerge
'resurface' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps you can see an association between them that I don't see?
'at body of water in the midlands they come together' is the wordplay.
'at' says to put letters next to each other.
'body of water in the midlands they' becomes 'ree' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'come together' becomes 'merge' (I've seen this before).
'ree' put next to 'merge' is 'REEMERGE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for reemerge that I've seen before include "Become visible again" , "Again become known" , "Come out again" , "appear again" .)
