Is there a difference between bilingual and multilingual people?

Yes, there is a difference between bilingual and multilingual people.

* Bilingual: A person who speaks two languages fluently.

* Multilingual: A person who speaks more than two languages fluently.

So, bilingualism is a subset of multilingualism. Everyone who is bilingual is also multilingual, but not everyone who is multilingual is bilingual.

Here's an analogy:

* Bilingual: Like having a car that runs on gasoline and electricity.

* Multilingual: Like having a car that runs on gasoline, electricity, and propane.

Both cars are able to function on multiple fuel sources, but the multilingual car has more options.
