largest of Canary Islands (8)
I believe the answer is:
tenerife
'largest of canary islands' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tenerife that I've seen before include "Fire teen off the island" , "Largest of the Canary Islands" , "Largest Canary island" , "One of the Canary Islands" , "holiday island" .)
