Ignorant, not cognisant (7)
I believe the answer is:
unaware
This clue is a double definition.
'ignorant' is the first definition.
(I've seen this in another clue)
'not cognisant' is the second definition.
(I've seen this before)
(Other definitions for unaware that I've seen before include "Not informed - ignorant (of)" , "Without knowledge" , "Unknowing" , "Ignorant - unconscious" , "Unwitting, not knowing" .)
