Here's why:
* No Official Language: Malayalam is not an official language of the UN. The official languages are English, French, Spanish, Russian, Chinese, and Arabic.
* Interpretation: While speakers can address the UN in their native language, their speeches are simultaneously interpreted into the official languages. This makes it difficult to track who was the "first" to use a particular language.
* Diverse Representation: Over the years, many Indian diplomats and representatives from other countries with Malayalam speakers have likely addressed the UN, using either their native language and having it interpreted or speaking directly in one of the official languages.
Therefore, pinpointing the first person to speak Malayalam at the UN is not a feasible task.
