International Mother Language Day (IMLD) is a worldwide observance celebrated annually on 21st February. It promotes awareness of cultural and linguistic diversity and international understanding through multilingualism and multiculturalism.


IMLD was an initiative of Bangladesh and the Bengali Language Movement. It was established in 1999 by the UN Educational, Scientific and Cultural Organization (UNESCO). The Bengali Language Movement was begun to honour three students from Dhaka University in Bangladesh, who were killed during a demonstration calling for the political recognition of their mother language, Bangla or Bengali, on 21st February 1952.

The passion behind IMLD has encouraged the establishment of many political conferences, which aim to address the needs and overcome the barriers to economic integration of those in diverse geopolitical circumstances around the world.

‘Languages are the most powerful instruments of preserving and developing our tangible and intangible heritage. All moves to promote the dissemination of mother tongues will serve not only to encourage linguistic diversity and multilingual education but also to develop fuller awareness of linguistic and cultural traditions throughout the world and to inspire solidarity based on understanding, tolerance and dialogue.’
Gibson, 2019

The significance of languages

UNESCO considers mother languages to be an essential part of culture and identity, values and knowledge – to be vital in the preservation and spread of traditions, rituals and forms of expression that make all our lives richer.

IMLD promotes the preservation and protection of all languages.

‘When a language is lost, it is not only the words and their meaning that disappear. It also involves a loss of unique cultural knowledge embodied in the language for centuries, including historical, spiritual and ecological knowledge.’, 2019

Why do languages disappear?

Languages disappear when their speakers do! This can happen due to internal factors, such as when a community has a negative attitude towards its own language and does not maintain or protect it from extinction, or due to external factors, such as when a government pursues a policy for a ‘lingua franca’.

Many other factors, such as migration, urbanisation, globalisation and the increasing worldwide spread of new technology, can have an adverse effect on language diversity, especially when traditional ways of life are threatened. At the same time, they can also help to protect, spread and preserve languages.

‘Researchers at the Jawaharlal Nehru University in India have made extensive recordings of Boa Sr., the last surviving speaker of the Bo language of the Andaman Islands in the Indian Ocean. Although she died in 2005, there is now a rich digital archive of materials, making the language and the cultural, historical and ecological knowledge that it relayed available to future generations that otherwise would have been lost to obscurity.‘
Araujo, 2019

Further research indicates the value of preserving languages:

’In some countries, a particular language might be preferred for political or cultural reasons. This can result in the domination of one language in education and other public services. People that don’t speak the dominant language or speak it poorly can thus be disadvantaged and in the worst cases, it can lead to discrimination in daily life, exclusion from jobs or services and even oppression. It can also result in other languages becoming endangered and ultimately extinct, but in countries that preserve the mother tongue and encourage the use of a child’s mother tongue helps to create a strong foundation for learning and gives them the building blocks they need.’
Karin & Islam, 2015

Protecting endangered languages

Languages are disappearing: a worldwide shared interest and commitment is needed to help them survive. As part of UNESCO’s work to promote mother languages and protect linguistic and cultural diversity, the organisation has created an online ‘Atlas of the World’s Languages in Danger’ (, 2019), to track and raise awareness of endangered languages and to safeguard the world’s linguistic diversity among governments, community representatives and the general public.

What can we do?

  • Celebrate ‘Language of the Term’ – learn key words and phrases in different languages.
  • Ask the children to complete and share projects in their home language - don't worry if you can't understand or mark it. It's about acknowledgement and participation in home language and the celebration of sharing each other's skills, as well as learning through that medium.
  • Ensure the outside community, parents and carers embrace and continue to speak their home language with their children by inviting them to take part in workshops that emphasise the value and power of their home language. Parents and carers can be encouraged to share their languages through shared stories or guest visits to school.
  • Encourage parents and carers to talk about their children's learning in their home language so that their home language is developed alongside the language of the school. This not only supports learners with developing academic literacy in their own language, but it enables the comprehension of concepts.
  • ​Make links with schools around the world and share languages and learning.
  • Rejoice in International Mother Language Day!

Languages are dying. It’s our duty to protect our heritage and that of others – let’s embrace and celebrate languages to keep them alive!

It's now almost exactly a year since the UK education system went into lockdown. The ruling that schools must close to almost all pupils was a shock to teachers, pupils, parents and everyone involved in the education system - and the repercussions of the immediate crisis continue to ripple through our lives.

What is the role of an EAL teacher?

An EAL teacher is a professional specialising in working with learners for whom English is an additional language, such as refugees, asylum seekers or children of migrant families.

In Science, EAL learners need to understand scientific language, both written and oral, as well as to work with the command verbs such as; discuss, explain, evaluate etc… (Mertin, 2014). This means the language required for Science is academic and challenging and, as a result, it can become extremely difficult for learners to access the subject content. This begs the questions; How do we make the lessons comprehensible to EAL learners and provide what Krashen (1998) terms as ‘comprehensible input’?
