How many official languages are recognized by the UN?

"recognized by the UN" is a lot different than "officially used by the UN", this question makes it seem like they don't see other languages as true languages.

Dragonlady, Arabic, Chinese, French, Spanish, Russian, and English. I'm unsure which Chinese language they mean, as there are two major ones.

India is the most populous country with more than 1.4 billion people yet its official language hindi is not still an official language at the UN. This organization needs urgent reforms

Listing the 6 languages in the explanation will have been expected.

Player #4236826, It's the simplified Chinese, official language of the People's Republic of China (Mainland China) that is an official language of the UN. Traditional Chinese is used in Taiwan (Republic of China)

Dragonlady, Oops, I mean five major ones.

So what are the 6 accepted languages?
