Ignorant peacekeepers tense when talking (8)
I believe the answer is:
untaught
'ignorant' is the definition.
(I've seen this in another clue)
'peacekeepers tense when talking' is the wordplay.
'peacekeepers' becomes 'un'.
'tense' becomes 't' (abbreviation used in many dictionaries).
'when talking' becomes 'aught' (I can't justify this - if you can you should give a lot more credence to this answer).
'un'+'t'+'aught'='UNTAUGHT'
Can you help me to learn more?
(Other definitions for untaught that I've seen before include "having learnt nothing?" , "excluded from lessons" , "Not acquired by education" , "Not educated" , "spontaneous" .)
