Official languages: in the constitution, in a statute, or nowhere at all
How the world celebratesIndia's constitution devotes an entire Part to language; Article 343 makes Hindi in Devanagari script the official language of the Union, with a fifteen-year transition clause for English. Indonesia's constitution settles it in one sentence — the language of the state is Indonesian. Brazil's Article 13 does the same. China's constitution never uses the phrase "official language"; it puts the promotion of standard spoken Chinese in the last line of the article about education. Taiwan goes the other way: its National Languages Development Act declines to name a single national language and instead lists every indigenous community's language, plus Taiwan Sign Language, as national languages of equal standing. Japan has no statutory official language at all. Neither the US constitution nor any act of Congress names one — English was designated by executive order in March 2025.

How does Brazil mark Official languages: in the constitution, in a statute, or nowhere at all?
Article 13 of Brazil's constitution: the Portuguese language is the official idiom of the Federative Republic of Brazil. One sentence, as blunt as Indonesia's — but the two paragraphs that follow reveal a different emphasis. The first lists the symbols of the republic: the flag, the anthem, the arms and the national seal. The language is written ahead of the symbols, in its own sentence, rather than sitting among flag, emblem and anthem as it does in Indonesia. The second paragraph says the states, the Federal District and the municipalities may have symbols of their own. So the same article does two things at once: it unifies language at the federal level and devolves symbolism to local government. That is the opposite direction from the United States, where the federal level stayed blank and the states designated for themselves — one unifies the language from above while distributing symbols from below; the other left even the language to the states. A great many indigenous and immigrant-community languages are still spoken in Brazil, and some municipalities have their own legislation making one of them co-official; that happens outside Article 13, at the local level.

How does China mark Official languages: in the constitution, in a statute, or nowhere at all?
China's constitution never uses the phrase "official language". Language appears in three separate places, and the scattering is itself the answer. Article 4, in the chapter on nationalities, says every nationality has the freedom to use and develop its own spoken and written language and to preserve or reform its own customs. Article 19 — which is the article about education — ends, after paragraphs on universal compulsory schooling and on secondary and higher education, with a single line: the state promotes the nationally used Putonghua. In the architecture of the constitution, in other words, promoting the standard language is not a status clause about language at all; it is an educational task. Article 121 then supplies the operational side: organs of self-government in national autonomous areas use, in performing their functions, the one or several languages in common use in that locality, as prescribed by its own autonomy regulations. Freedom in the nationalities chapter, promotion in the education chapter, actual use in the autonomy chapter — and nowhere a sentence beginning "the official language of the state is".

How does Indonesia mark Official languages: in the constitution, in a statute, or nowhere at all?
Indonesia's constitution settles it in one sentence: Article 36 — the language of the state is Indonesian. No conditions, no transition clause, no list of exceptions. To feel the weight of that sentence you have to see where it sits: around Article 36 are the flag (Article 35), the state emblem with the motto "unity in diversity" (Article 36A), and the national anthem (Article 36B). Language is placed among the symbols of the state, alongside flag, emblem and anthem. That is a completely different filing decision from India's, which puts language in a Part about administrative operation, or China's, which scatters it between the chapters on nationalities and on education. And the historical weight sits there too: Indonesian is not the mother tongue of the largest group — Javanese is — but a variety of Malay chosen as the common language. Writing it in among the symbols amounts to declaring that this country's unity was chosen rather than inherited. Article 36C then leaves the details of flag, language, emblem and anthem to statute.

How does India mark Official languages: in the constitution, in a statute, or nowhere at all?
India is the only one of these seven markets whose constitution devotes a whole Part to language. Article 343(1): the official language of the Union shall be Hindi in Devanagari script, and the numerals for official purposes of the Union shall be the international form of Indian numerals. That even the choice of numeral forms is written into the constitution says something about how concrete the arguments were. Clause (2) then sets a fifteen-year transition: for fifteen years from the commencement of the constitution, English continues to be used for all the official purposes of the Union for which it was being used before. That fifteen-year clause is the pivotal design in Indian language politics — it wrote in an endpoint, and what actually happened as the endpoint approached produced further legislation and amendment. The Part also handles the official languages of the states, the language of communication between one state and another, and the language of the Supreme Court and the High Courts. Next to the one-sentence settlements of Indonesia and Brazil, India is not answering "which language" but how the levels of a multilingual state speak to one another.

How does Japan mark Official languages: in the constitution, in a statute, or nowhere at all?
Japan has no statutory official language. The constitution does not use the term, and no act designates Japanese as official. In practice Japanese is used as a matter of course, but that rests on convention and on how individual statutes are administered, not on any provision declaring it. The closest thing is the Act on the Promotion of Japanese Language Education (Act No. 48 of 2019) — and as its title says, what it governs is the promotion of teaching, not the conferring of status: it sets out measures to widen access to Japanese-language education at home and abroad, to maintain and raise its standard, and to fund research. The absence of a designating provision is itself meaningful in this seven-way comparison: India spent a whole Part on it, Indonesia and Brazil each settled it in a sentence, the United States designated one by executive order after the fact. Japan has done none of these.

How does Taiwan mark Official languages: in the constitution, in a statute, or nowhere at all?
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.

How does United States mark Official languages: in the constitution, in a statute, or nowhere at all?
The United States constitution names no official language, and Congress has never passed a statute doing so. That blank stood for more than two centuries, until 6 March 2025, when an executive order titled "Designating English as the Official Language of the United States" was published in the Federal Register. The instrument was an executive order — not a constitutional amendment and not an act of Congress — and that is what makes this entry worth looking at: the same decision sits in the constitution in India and Indonesia, in a statute in Taiwan, and in a late executive proclamation in the United States. Different levels mean different ways of being undone: a constitutional clause takes an amendment, a statute takes Congress, an executive order can be revoked by the next president with a signature. It is also worth separating federal from state: while the federal level stayed blank, most states had long since designated English in their own constitutions or codes, so "does the United States have an official language" gets different answers at the two levels.
