Ignorant woman joined conflict to the east (7)
I believe the answer is:
unaware
'ignorant' is the definition.
(I've seen this before)
'woman joined conflict to the east' is the wordplay.
'woman' becomes 'una' ().
'joined' is a charade indicator (letters next to each other).
'conflict' becomes 'war' (war is a kind of conflict).
'to the east' becomes 'E' (abbreviation).
'una'+'war'+'e'='UNAWARE'
(Other definitions for unaware that I've seen before include "Ignorant - unenlightened" , "Not conscious of what is going on" , "Not having knowledge or realisation" , "Lacking knowledge (of a situation or fact)" , "Innocent" .)
