Stupidity concealed by sovereign or ancestors? (9)
I believe the answer is:
ignorance
'stupidity' is the definition.
(I've seen this before)
'concealed by sovereign or ancestors?' is the wordplay.
'concealed by' indicates the answer is hidden within the clue.
'IGNORANCE' is hidden within 'sovereign or ancestors'.
(Other definitions for ignorance that I've seen before include "Nescience" , "Being in the dark" , "Ken lacking" , "may be considered bliss" , "Lack of education" .)
