Perhaps Irish saga elicits something occult (6)
I believe the answer is:
gaelic
'perhaps irish' is the definition.
(Irish Gaelic)
'saga elicits something occult' is the wordplay.
'something occult' says the answer is hidden in the clue (hidden or \'occult\' part of the clue).
'GAELIC' is hidden within 'saga elicits'.
(Other definitions for gaelic that I've seen before include "Irish language or Celtic language of Scotland" , "Characteristic of the Celts" , "Speech" , "The native language of Ireland" , "Language of the Celts" .)
