21 February – International Mother Language Day

What is the mother tongue?

Is it a language that we learn from mother or a language we are closest to? Is mother tongue the language that we speak best? Can mother tongue also be a language no longer spoken?

If you are interested in different perspectives on defining the mother tongue, take a look at the terminology section Bilingualism, available to the public as part of the Terminology Portal.
