Where, abroad, the people have an air about them (7)
I believe the answer is:
armenia
'where abroad' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'people have an air about them' is the wordplay.
'people have' becomes 'men' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'an air' becomes 'aria' (I've seen this in another clue).
'about them' means one lot of letters goes inside another.
'men' going within 'aria' is 'ARMENIA'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for armenia that I've seen before include "Transcaucasian nation" , "Landlocked country south of Georgia" , "Mountainous republic bordering Turkey" , "South-west Asian country, capital Yerevan" , "Republic east of Black Sea bordering Turkey, capital Yerevan" .)
