A speaker or two, at the Centre (6)
I believe the answer is:
orator
'a speaker' is the definition.
(I know that speaker can be written as orator)
'or two at the centre' is the wordplay.
I cannot really understand how this works, but
'or' is present in the answer.
'at' is present in the answer.
The remaining letters 'or' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for orator that I've seen before include "One addressing" , "He lectures" , "Eloquent public speaker" , "A fluent public speaker" , "Eloquent type" .)
