Speaker of many languages (8)
I believe the answer is:
polyglot
'speaker of many languages' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for polyglot that I've seen before include "One fluent in many languages" , "Multilingual person" , "Having say French and Italian" , "Having command of many languages" , "Person who knows several languages" .)
