While some countries have multiple official languages, every country recognizes at least one language as its national language, even if it's not explicitly codified as such.
It's important to remember that "national language" can have different meanings:
* Official language: A language recognized by the government for use in official contexts like laws, education, and administration.
* National language: A language that is widely used and considered to be the language of the nation, often tied to a sense of national identity.
While some countries may not explicitly declare a national language, they usually have a language that serves this function in practice.
