I have innate artlessness (7)
I believe the answer is:
naivete
'artlessness' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for naivete that I've seen before include "Quality of the simple" , "Lack of worldliness" , "Greenness" , "Ingenuousness" , "Being green" .)
