Lack of knowledge (9)

Ross

I think it could be either:

ignorance

nescience

'lack of knowledge' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for nescience that I've seen before include "Lack of awareness" , "Lack of knowledge" , "Literary word for ignorance" .)

I've seen this clue in The Times, The Mirror, The Independent, the Sydney Morning Herald, The Guardian and The Star Tribune.
