New native quarter shows simplicity (7)
I believe the answer is:
naivete
'simplicity' is the definition.
(I've seen this before)
'new native quarter' is the wordplay.
'new' indicates anagramming the letters.
'quarter' becomes 'e'.
'native' with letters rearranged gives 'naivet'.
'naivet'+'e'='NAIVETE'
'shows' acts as a link.
(Other definitions for naivete that I've seen before include "Ingenuousness" , "natural simplicity" , "Innocence or guillibility" , "Ingenuosity" , "Quality of innocent gullibility" .)
