Topic: Official Languages by Country: Who Decides?

What does Taiwan require?

Everyday topic

Taiwan's approach is unique among these seven markets: it declines to name a single national language. Article 3 of the National Languages Development Act defines national languages as the natural languages used by each of Taiwan's indigenous communities and Taiwan Sign Language; Article 4 then states that all national languages are equal and that no one may be discriminated against or restricted for using them. The statute does not elevate one language out of many — it takes them in as a set and declares them equal to one another. That sign language sits in the same list is the clearest evidence of what is meant: a national language here is defined as one that people on this island actually use, not one the government works in. Article 7 adds that languages facing a break in transmission get priority for revitalisation. It is the mirror image of the Indian structure, which names one language and then legislates separately for everything else.

What is this topic?

Which language is official depends on where the rule lives: Indonesia and Brazil name a state language in their constitutions, India sets the Union's official language in its constitution, China promotes Putonghua through an education clause without naming an "official language", and the United States designated English by executive order in 2025.

Japan has no statutory official language, while Taiwan recognises multiple national languages.

🗳️ What about you?

Is the language you speak at home the same one used at school and in government offices?
