The mount where Noah's ark landed (6)
I believe the answer is:
ararat
'the mount where noah's ark landed' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ararat that I've seen before include "Mount (the Ark''s last resting place)" , "Mountain where the Ark grounded" , "Biblical mount" , "Turkish Mount on which Noah's Ark is said to lie" , "Biblical mountain" .)
