A speaker who is skilled at splitting alternatives (6)
I believe the answer is:
orator
'a speaker' is the definition.
(I know that orator is a type of speaker)
'is skilled at splitting alternatives' is the wordplay.
I cannot quite understand how this works, but
'at' is found in the answer.
This explanation may well be incorrect...
'who' acts as a link.
Can you help me to learn more?
(Other definitions for orator that I've seen before include "Eloquent type" , "One addressing" , "An impressive public speaker" , "A gifted public speaker" , "One who holds forth" .)
