Passage from bachata hit irks island (6)
I believe the answer is:
tahiti
'island' is the definition.
(I know that Tahiti is a island)
'passage from bachata hit irks' is the wordplay.
'passage from' says the answer is hidden in the clue (a sequence or passage of letters from the clue).
'TAHITI' is hidden in the letters of 'bachata hit irks'.
(Other definitions for tahiti that I've seen before include "Main island of French Polynesia" , "South Pacific island, linked to Paul Gauguin and Robert Louis Stevenson" , "An isle in the South Seas" , "Pacific island, the largest in French Polynesia" , "part of Polynesia" .)
