Facilities near the borders of Kosovo upset observer (7)
I believe the answer is:
lookout
'observer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'facilities near the borders of kosovo upset' is the wordplay.
'facilities' becomes 'loo' (I've seen this in other clues).
'near the' is a charade indicator (letters next to each other).
'borders of' suggests removing the centre.
'upset' becomes 'ut' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'kosovo' with its middle taken out is 'ko'.
'loo'+'ko'+'ut'='LOOKOUT'
Can you help me to learn more?
(Other definitions for lookout that I've seen before include "Person set to watch" , "Observation point" , "Guard on duty" , "Be careful!" , "Person keeping watch" .)
