Union-member holds key to golden gate, for example? (6)
I believe the answer is:
bridge
'golden gate for example?' is the definition.
(golden gate is a kind of bridge)
'union-member holds key' is the wordplay.
'union member' becomes 'bride' (I've seen this in other clues).
'holds' indicates putting letters inside.
'key' becomes 'g' (I've seen this in other clues).
'bride' going around 'g' is 'BRIDGE'.
'to' acts as a link.
(Other definitions for bridge that I've seen before include "Card game - pontoon - couple" , "''Like a ... over troubled water'' (Simon and Garfunkel)" , "Span or connect" , "Span, connecting structure" , "Span of popular card game" .)
