Port gets Ray drunk (3)
I believe the answer is:
ayr
'port' is the definition.
(I know that Ayr is a port)
'ray drunk' is the wordplay.
'drunk' indicates an anagram.
'ray' anagrammed gives 'AYR'.
'gets' acts as a link.
(Other definitions for ayr that I've seen before include "Scottish salmon river" , "Scottish city" , "Scottish resort" , "Scots. town; sounds like song" , "Scottish town sounds tuneful" .)
