Elements of game show come together (4)
I believe the answer is:
mesh
'come together' is the definition.
(I've seen this in another clue)
'elements of game show' is the wordplay.
'elements of' indicates a hidden word (elements or parts of the clue).
'MESH' is hidden in the letters of 'game show'.
(Other definitions for mesh that I've seen before include "Lattice" , "Knit or weave for Shem" , "Engage; net" , "Interlock" , "Engagement" .)
