Game of golf hosted by newlywed (6)
I believe the answer is:
bridge
'game' is the definition.
(card game)
'golf hosted by newlywed' is the wordplay.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'hosted by' means one lot of letters goes inside another.
'newlywed' becomes 'bride' (newlywed woman).
'g' going into 'bride' is 'BRIDGE'.
'of' is the link.
(Other definitions for bridge that I've seen before include "Can be contract or cantilever" , "Partial denture; span" , "Structure spanning a divide" , "part for violin" , "Crossing point" .)
