They sweep bedrooms when Ed's away (6)
I believe the answer is:
brooms
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe there's a link between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for brooms that I've seen before include "Sweeping brushes and various shrubs" , "Sweepers" , "Sweeping implements and shrubs" .)
