What does bi-lingual mean?

The term bilingual means "two languages" and may refer to a location, or a publication, or a person. A bilingual individual is one who can speak (or more specifically, speak fluently) in 2 different languages.

In Canada both English and French are taught because Canada is a bilingual country.

There is a term for speaking three languages (trilingual), but more common is the term "multilingual" meaning able to speak several languages.

• able to speak and understand two languages
• written in two languages.

Bilingual means that you can speak more than one language.
A person is bilingual if he or she can speak two languages (such as Spanish and English) fluently. (To be fluent in a language means that you can speak and write it well.)
