Cardiff is the largest city in Wales and serves as the political, cultural, and economic centre of the country. The city has two official languages, Welsh and English, recognised through Welsh language legislation and public services.
English is the most widely used everyday language in Cardiff. Welsh is the national language of Wales and has a strong presence through schools, government services, cultural organisations, and Welsh-speaking communities.
The city also has residents who speak languages connected with international migration. Communities from South Asia, Europe, Africa, and other regions contribute languages such as Polish, Arabic, Bengali, Somali, Urdu, Punjabi, and Mandarin.
The linguistic identity of Cardiff has developed through several historical periods, including the growth of the coal industry, international trade, university expansion, and modern migration. This creates a city where multiple languages are used in homes, workplaces, schools, and public spaces.
Why are Welsh and English the main languages in Cardiff?
Welsh and English became the main languages of Cardiff because of Wales’ historical development, legal recognition of Welsh, and the widespread use of English in administration, commerce, education, and everyday communication.
Welsh is a Celtic language with roots extending back more than 1,500 years. It developed from the Brythonic languages spoken in Britain before the Anglo-Saxon period.
English became dominant in many parts of Wales through political, economic, and industrial changes. Cardiff’s growth as a port city increased the use of English because international business, shipping, and administration operated largely in English.
The Welsh Language Act 1993 and the Welsh Language (Wales) Measure 2011 strengthened the official status of Welsh. These laws established equal treatment principles for Welsh and English in public services.
The Welsh Government promotes Welsh through education, media, and public communication. Organisations such as the Welsh Language Commissioner support the use of Welsh in public life.
Cardiff reflects this bilingual framework through bilingual road signs, government communications, cultural events, and educational opportunities.
How common is Welsh in Cardiff?
Welsh is spoken by a significant number of Cardiff residents, with thousands using the language daily at home, in schools, workplaces, and cultural settings. Welsh-medium education has increased the number of younger speakers across the city.
According to the Office for National Statistics Census 2021, around 17.8% of Cardiff residents aged three and over reported being able to speak Welsh. This represents tens of thousands of people across the capital.
Welsh-speaking communities are particularly connected with areas such as Canton, Grangetown, and parts of north Cardiff. Welsh-medium schools have played a major role in increasing language skills among younger generations.
Schools including Welsh-medium primary and secondary institutions provide education where Welsh is the main teaching language. These schools support children from both Welsh-speaking families and families choosing bilingual education.
Welsh is also visible through cultural organisations, festivals, literature, music, and broadcasting. Events connected with Welsh culture provide opportunities for residents and visitors to experience the language.

How has Cardiff’s language history developed?
Cardiff’s language history has changed through centuries of political transformation, industrial expansion, migration, and cultural development. The city moved from a Welsh-speaking settlement to a bilingual capital with a diverse modern language environment.
Cardiff began as a small settlement influenced by Welsh-speaking communities. During the medieval period, Welsh remained central to local communication.
The Industrial Revolution transformed Cardiff into a major coal-exporting port. From the nineteenth century onwards, workers and traders arrived from different parts of Britain and overseas.
The expansion of Cardiff Docks created international connections with countries across Europe, Africa, and the Middle East. This increased linguistic diversity within the city.
Cardiff became the capital of Wales in 1955, increasing its importance as a centre for Welsh government, culture, and identity. The establishment of national institutions strengthened the role of Welsh in public life.
Modern Cardiff combines historical Welsh language traditions with the languages introduced by global communities.
Which immigrant languages are spoken in Cardiff?
Cardiff has many immigrant and community languages because of international migration, university populations, employment opportunities, and historic links with global regions. These languages represent the city’s multicultural population.
Common community languages spoken in Cardiff include Polish, Arabic, Bengali, Urdu, Punjabi, Somali, Mandarin, Spanish, Portuguese, and Romanian.
The Polish-speaking community expanded significantly after Poland joined the European Union in 2004, leading to increased migration across the United Kingdom.
South Asian languages have a long presence in Cardiff. Communities using Urdu, Punjabi, Bengali, and other languages contribute to the city’s cultural and commercial life.
Arabic is spoken by Cardiff residents from several countries, including communities connected with the Middle East and North Africa.
Cardiff’s universities also attract international students who bring languages from Asia, Europe, Africa, and the Americas.

How is Cardiff becoming more multilingual in the future?
