Local youngster displaying attitude in confines of Brechin (5)
I believe the answer is:
bairn
'local youngster' is the definition.
'bairn' can be an answer for 'youngster' (bairn is a kind of youngster). I'm not certain of the 'local' bit.
'attitude in confines of brechin' is the wordplay.
'attitude' becomes 'air' (I've seen this before).
'in' is an insertion indicator.
'confines of' says to hollow out the word (remove centre letters) (the letters at the borders or confines are used).
'brechin' with its centre removed is 'bn'.
'air' put into 'bn' is 'BAIRN'.
'displaying' is the link.
Can you help me to learn more?
(Other definitions for bairn that I've seen before include "little one in Yorkshire" , "A Scottish child?" , "A tot of Scotch" , "Child (of the North!)" , "Kid" .)
