Sport partnerships created beside the sea, where one might tee off, perhaps? (4,5)
I believe the answer is:
golf links
'beside the sea where one might tee off perhaps?' is the definition.
I can't tell whether this defines the answer.
'sport partnerships' is the wordplay.
'sport' becomes 'golf' (golf is a kind of sport).
'partnerships' becomes 'links' (I can't justify this - if you can you should believe this answer much more).
'golf'+'links'='GOLF-LINKS'
'created' acts as a link.
Can you help me to learn more?
(Another definition for golf links that I've seen is " Seaside leisure facility".)
