Sweeper in drama school? Right (5)
I believe the answer is:
radar
'sweeper' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'drama school? right' is the wordplay.
'drama school?' becomes 'RADA' (Royal Academy of Dramatic Art).
'right' becomes 'r' (abbreviation).
'rada'+'r'='RADAR'
'in' is the link.
Can you help me to learn more?
(Other definitions for radar that I've seen before include "Range and direction finding equipment" , "Locator that uses a microwave echo" , "System for detecting objects with radio waves" , "Gluttony" , "Electronic rangefinder" .)
