Usage

What does bilingual mean? Bilingual is most commonly used to describe someone who can speak or understand two languages, especially with some level of fluency. It can also be used to describe things that involve or that are written or spoken in two languages, as in These instructions are bilingual—they’re written in English and Spanish. The similar terms trilingual and multilingual are used in the same way, with trilingual indicating three languages and multilingual indicating more than two and especially several languages. The ability to speak two languages or the use of two languages is called bilingualism. Example: Being bilingual is a great advantage for many job seekers.

Etymology

Origin of bilingual

1835–45; < Latin bilingu ( is ) ( bi- bi- ¹ + lingu-, stem of lingua tongue + -is adj. suffix) + -al ¹

Explanation

Bilingual is an adjective that describes a person or community that speaks two languages. A bilingual woman might speak Spanish and English, and a part of town where people speak Mandarin and Polish is a bilingual neighborhood. The prefix bi- means “having two,” and the Latin word lingua means “tongue, language,” so bilingual literally means “having two tongues.” It would be a mouthful to have two physical tongues, but luckily bilingual is for language tongues: the ability to speak two languages fluently. Bilingual is also a noun, and a person can be called a bilingual, like in the African country Chad, where the official languages are French and Arabic, and where many of the citizens are bilinguals.
