They can't have any choice (7)
I believe the answer is:
beggars
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for beggars that I've seen before include "Mendicants" , "Bums" , "'If wishes were horses . . . . . . . would ride'" .)
