South American soldier with weapon (always article to be carried) (10)
I believe the answer is:
paraguayan
'south american' is the definition.
(Paraguayan is an example)
'soldier with weapon always article to be carried' is the wordplay.
'soldier with' becomes 'para' (paratrooper. I am not sure about the 'with' bit.).
'weapon' becomes 'gun' (gun is a kind of weapon).
'always' becomes 'ay' (archaic term for 'always').
'article' becomes 'a' (the indefinite article in English).
'to be carried' means one lot of letters goes inside another (one word carried by another word).
'ay'+'a'='aya'
'gun' enclosing 'aya' is 'guayan'.
'para'+'guayan'='PARAGUAYAN'
Can you help me to learn more?
(Other definitions for paraguayan that I've seen before include "From Asuncion, perhaps" , "South American" .)
