Farmer George hosts get together (5)
I believe the answer is:
merge
'get together' is the definition.
(I've seen this in another clue)
'farmer george hosts' is the wordplay.
'hosts' says the answer is hidden in the clue.
'MERGE' can be found hidden inside 'farmer george'.
(Other definitions for merge that I've seen before include "Join into one" , "Combine into one" , "Combine elements" , "Mix" , "Combine, blend" .)
