One shutting eyes to reality in east of Germany elaborately decorated (7)
I believe the answer is:
ostrich
'one shutting eyes to reality' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'east of germany elaborately decorated' is the wordplay.
'east of germany' becomes 'ost' ('east' in German).
'elaborately decorated' becomes 'rich' (I've seen this before).
'ost'+'rich'='OSTRICH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ostrich that I've seen before include "Runner" , "Someone unprepared to face the facts" , "Long-necked bird" , "source of showy feathers" , "Torch is held over large bird" .)
