Scamp puts on British accent (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
brogue
'accent' is the definition.
(brogue can mean a Scottish or Irish accent)
'scamp puts on british' is the wordplay.
'scamp' becomes 'rogue' (I've seen this before).
'puts on' means one lot of letters go next to another (in a down clue, some letters go on top of others).
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'rogue' put after 'b' is 'BROGUE'.
(Other definitions for brogue that I've seen before include "may be on a member's end" , "Outdoor shoe; accent" , "Patterned shoe, accent" , "Stout shoe - Irish accent" , "Worn" .)
