American providing security at Uncle's? (6)
I believe the answer is:
pawnee
'american' is the definition.
(Pawnee is an example)
'security at uncle's?' is the wordplay.
'security' becomes 'pawn' (I've seen this before).
'at uncle's?' becomes 'ee' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pawn'+'ee'='PAWNEE'
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for pawnee that I've seen before include "North American Indian - one taking a pledge" , "N American native" , "one living in America" .)
