Bridge close to Swiss golf course (5)
I believe the answer is:
links
'golf course' is the definition.
(I know that Links is a type of golf course)
'bridge close to swiss' is the wordplay.
'bridge' becomes 'link' (both can mean to join).
'close to' says to take the final letters (the 'close' to the word).
The final letter of 'swiss' is 's'.
'link'+'s'='LINKS'
(Other definitions for links that I've seen before include "course for sportspeople" , "Joins on the golf course?" , "Shore-side golf course - connects" , "Bits of chain" , "Bonds" .)
