Get engaged during game show (4)
I believe the answer is:
mesh
'get engaged' is the definition.
(to mesh is to become engaged or joined)
'during game show' is the wordplay.
'during' says the answer is hidden in the clue.
'MESH' is hidden in the letters of 'game show'.
(Other definitions for mesh that I've seen before include "Interweave - netting" , "Trap" , "Undeviating" , "Net, snare" , "Get engaged" .)
