Concept:
One-word substitution requires knowing the specific definitions and roots of descriptive nouns.
• Prefix 'Poly-': Means "many" or "much" (as in polygon or polymer).
• Root 'Glot': Comes from the Greek word for "tongue" or "language."
Step 1: Differentiating between the options.
A
Linguist studies the science of language, not necessarily speaks many.
An
Orator is a person who is a skilled public speaker.
A
Translator converts written text from one language to another.
Step 2: Defining the correct term.
A
Polyglot is a person who
knows and speaks several languages.
The term focuses on the multilingual ability of the individual.
While a polyglot might be a linguist or a translator, the most direct word for the ability to speak many languages is Polyglot.
