From Donegal (5)
I believe the answer is:
irish
'from donegal' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for irish that I've seen before include "Sort of coffee, stew or terrier" , "Kind of whiskey" , "of European country" , "Reddish-brown dog" , "From Eire" .)
