Curt, British queen taken in by trick (7)
I believe the answer is:
brusque
'curt' is the definition.
('brusque' can be a synonym of 'curt')
'british queen taken in by trick' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'queen' becomes 'qu'.
'taken in by' indicates putting letters inside.
'trick' becomes 'ruse' (I've seen this before).
'qu' put inside 'ruse' is 'rusque'.
'b'+'rusque'='BRUSQUE'
(Other definitions for brusque that I've seen before include "Curt, blunt" , "Curt in speech" , "Blunt and uncivil" , "Abrupt, offhand" , "Short" .)
