Speaker using some words on a rota system? (6)
I believe the answer is:
orator
'speaker' is the definition.
(orator is a kind of speaker)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for orator that I've seen before include "He addresses" , "He lectures" , "Skilled public speaker" , "A gifted public speaker" , "he can talk" .)
