UN area protected by British force in hot situations (6)
I believe the answer is:
saunas
'hot situations' is the definition.
Although both the answer and definition are plural nouns, I don't understand how one could define the other.
'un area protected by british force' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'protected by' is an insertion indicator.
'british force' becomes 'sas' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'un'+'a'='una'
'una' placed inside 'sas' is 'SAUNAS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for saunas that I've seen before include "Finnish steam baths" , "Sweat rooms" .)
