When Chile's capital is in alliance to Paraguay's (8)
I believe the answer is:
asuncion
'paraguay's' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'when chile's capital is in alliance' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'capital' indicates taking the first letters.
'is in' indicates putting letters inside.
'alliance' becomes 'union' (I've seen this before).
The first letter of 'chile' is 'c'.
'c' inserted inside 'union' is 'uncion'.
'as'+'uncion'='ASUNCION'
'to' is the link.
Can you help me to learn more?
(Other definitions for asuncion that I've seen before include "Capital of Paraquay" , "Capital city of Paraguay" , "South American capital city" .)
