Dorothy's speakers (6)
I believe the answer is:
sayers
'dorothy's' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for sayers that I've seen before include "Peig and Dorothy L." , "Dorothy L. --, novelist" , "detective story writer" , "They claim" , "she wrote mysteries" .)
