Sets up agency introducing the French to golf - a very Irish sport? (6)
I believe the answer is:
gaelic
'sport?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gaelic that I've seen before include "Language of the Celts" , "tongue" , "Irish language or Celtic language of Scotland" , "Characteristic of the Celts" , "The native language of Ireland" .)
